1 ADDENDUM TO THE STC PRO LOGGER II MANUAL 1. Probe Test for Testing Double Insulated Appliances (Utilities Menu) The SafeTcheck Pro Logger II now has a new feature Probe Test, available on all testers with Firmware Version V4.46 and above. By default Pro Loggers use the unique feature CheckConnect in conjunction with a Stainless Steel Cloak to perform an Insulation Resistance (IR) test on Double Insulated Appliances. CheckConnect ensures the Device Under Test (DUT) is both correctly connected to the Pro Logger (to provide a return path for leakage currents) and its exposed surfaces adequately covered to reduce the chance of an erroneous test result. During a Probe Test the CheckConnect feature is disabled. This gives the operator the ability to use the probe, the cloak or a combination of both to test Double Insulated Appliances. The test also provides adequate time to move the probe to several points on the DUT s surface before the test is complete. WARNING: Unlike CheckConnect the Probe Test does not look for a completed return circuit. A test conducted without a return circuit is an invalid test; unfortunately the Pro Logger II will still indicate a PASS test result. In some cases the operator may find that the Probe Test is more appropriate or convenient e.g. the size or physical location of the DUT may make it difficult to use the cloak or CheckConnect. To switch between the Double Insulated Probe Test and CheckConnect Options, go to the Utilities Menu under the F2 Key, Scroll down to the CheckConnect Option using the F2 Key and then select the required option. The selected option will always have a small rectangle to its right. NOTES: 1. TRIO Smartcal recommends the use of CheckConnect for most, if not all, IR tests on Double Insulated appliances. Failure to use this option with an incorrectly connected appliance may mean the test result is incorrect. This potentially dangerous situation exists with any Portable Appliance Tester without CheckConnect (please refer to the Warning above). 2. Correct use of the Cloak and CheckConnect is recommended to protect the operator from electric shock. This feature complies with the mandatory Safety Standard AS SAFETY OF MACHINERY DESIGN AND OPERATION. Notice Issued: 28 th September 2012 Page 1 of 6

2 2. Three (3) Pin Class 2 Run Test (Other Appliance Menu) Appliances connected to the mains via a 3 pin plug with no Double Insulated (Class 2) symbol visible, should be considered Earthed Appliances (Class 1), however, with some appliances of this kind, the earth conductor provides not only a degree of electrical safety but also a path to conduct EMI currents, to reduce noise. This EMI current may cause an appliance to fail due to, what the Pro Logger sees, as excessive leakage. Also, with some other appliances, there is simply no practical way of finding a connection to the Earth Conductor i.e. it has no exposed earthed metal parts. To test these appliances, a Three (3) Pin Class 2 Run Test has been provided (via the Other Appliance Menu) with the Pro Logger. The first phase of this test, while running the appliance, looks for 1mA of leakage current between the Pro Logger s Cloak and the appliance s case i.e. a standard Double Insulated Run Test. If the Pro Logger measures more than this, it will try again with an increased 5mA threshold (because the appliance is Earthed, up to 5mA of Leakage Current is permissible). The person conducting the test will be warned that the 1mA threshold has been exceeded and that a 5mA test will be conducted. Any more than 5mA of leakage current will cause the test to fail. NOTE: This test does not look for the presence of an Earth Conductor. It should only be used if the normal Earthed Appliance Insulation Resistance Test continually has failed. 3. Additional function to discard failed Electrical Tests (Database function) A new feature has been added to the Data Logging function that gives a user the option to discard a failed Electrical Test is available on all testers with Firmware Version V4.56 and above. With the Data Logging Enabled, if an Electrical Test fails, then the user will be prompted to either: save the test information by selecting Start, or abandon the information by selecting Reset. This feature greatly reduces the number of records stored in the Pro Logger s memory. It also reduces the time for editing the resultant data file, if bad test data has been logged to memory i.e. a failed test that is not an Electrical Fail but the result of incorrect connection or setup.

3 4. Additional Two (2) Wire Lead Test (Lead Test function) Many modern appliances use a two wire mains power lead with a figure 8 style socket i.e. no earth conductor. The Pro Logger s Lead Test will now test this style lead as a Class 2 appliance (requires an adaptor STCIEC2F8). The Pro Logger will conduct an Insulation Resistance (IR) Test if the lead is found to have no earth by design (requires confirmation by the user). The IR is measured between the inner mains conductors and the Pro Logger s Cloak which is wrapped around the length of the lead. This feature is available on all testers with Firmware Version V4.64 and above 5. User option to bypass a Failed Continuity (Double Insulated & Earthed Appliance Test functions) (Utilities Menu - V5.20 only) While performing Insulation Resistance (IR) tests on Double Insulated or Earthed Appliances, it may be difficult, or even impossible, to complete the test because of a reported Continuity Failure. This may be a result of the appliance s Mains or On/Off Switch not being closed; or the Pro Logger interpreting a closed switch with high impedance, as not closed. If the Pro Logger reports a Continuity Failure, the Pro Logger presents the user with an option to bypass the error and proceed to the IR test. A user should only proceed if the following is true: 1. the user is satisfied that the appliance s mains switch is closed; and 2. the mains switch doesn t require mains power to be activated. This may be occur when testing Phone Battery chargers such as those for iphones. Applies to Firmware Version V4.67 to V5.09 & Hardware V7.0 For Firmware V5.20 and above & Hardware V8.0 this function may be turned on or off by selecting Fail on poor cont via the Utilities Menu (F2 Key). NOTE: If in doubt, do not bypass the Continuity Failure error. Always err on the side of caution and consider the test a failure. Notice Issued: 28 th September 2012 Page 3 of 6

4 6. RCD Trip Time Threshold (Portable 30mA RCD Test function) When testing Portable RCDs the trip current is suddenly applied and the trip time measured. In the case of 30mA Portable RCDs the acceptable trip time is 300mS however at 150mS (a threshold considered good practice AS37060:2010) the Pro Logger will fail the RCD in Firmware below Firmware Version V4.46; for V4.46 and above the Pro Logger will provide the user with a warning (not a fail) if the Trip Time is 150mS but 300mS. 7. Results Dump (Database function) A results dump function has been added to all Pro Logger IIs to enable test data to be streamed directly into 3 rd party software packages. While using the Pro Logger II in conjunction with FASTtag Asset Management Software, test data may be streamed directly to FASTtag s database; either in real time or after the completion of tests. The onboard database must be disabled (via the Utilities Menu) if results are streamed to the FASTtag Software in real time. Notice Issued: 28 th September 2012 Page 4 of 6

5 8. Three (3) Phase Run Test Option (Other Appliance Menu) Optional run (current leakage) testing of Portable 3 Phase Appliances in accordance with AS/NZS This option is available with 20 and/or 32A 3 phase sockets or other current ratings as requested. The test (via the Other Appliance Menu) looks for an Earth Connection <= 1 Ohm; a run current to ensure the appliance is switched on and running; and a leakage current of <= 5mA. The test is a Long Run Test. It may be shortened at any time after the test commences by pressing Reset twice in quick succession. If any of the test parameters (Earth Current, Run Current or Leakage Current) fail, then the 3 phase test fails otherwise the Pro Logger will indicate a pass. This test requires 2 connections to the Pro Logger: an earth return connection to the Device Under Test s (DUT) chassis; and a connection the 20 or 32A 3 phase socket adaptor (this is a din type socket in the well of the Pro Logger II). The 3 phase socket adaptor is plugged into a 3 phase power source, then the DUT into the 3 phase adaptor. The DUT should be running to conduct a test. To test a 3 phase extension lead, run a test with the extension lead connected between an already tested (and passed) 3 phase appliance and the 3 phase adaptor.

To enter Battery mode press Start until the Pro Logger beeps (battery symbol in the bottom left corner of display will appear in this mode) 3. In Battery mode the Pro Logger will automatically shut down after 3 minutes, if no key is pressed 4. The Pro Logger may be switched from battery to mains without losing power (the battery will not charge in this mode - see Battery Charge Mode) 5. Failing to follow these instructions will reduce battery life and void the battery s warranty For a new Pro Logger ensure the battery is initially fully charged: 1. Power the Pro Logger from mains power 2. Set the Pro Logger into Charge mode (see below) 3. Wait for Charge Complete prompt to appear and then press Start 4. Turn the Pro Logger off by disconnecting the mains power Battery Charge Mode (following these steps will extend the life of the battery): 1. Power the Pro Logger from mains power (If already on, switch off and back on again) 2. The prompt select test needs to be displayed (If in database mode, press reset unil select test is displayed). The Battery will now be charging 3. Wait for the Charge complete prompt to appear 4. Press Start to acknowledge the charged condition 5. When fully charged the Pro Logger may be stored or it is ready for appliance testing NOTE: 1. While charging, do not select any tests, this will disable the battery charge mode (if this occurs, remove the mains power and restart the Battery Charge Mode sequence). 2. The battery will not charge while the Pro Logger is in Test mode 3. A low battery condition will display a screen message Low battery reconnect to mains 4. Storing the Pro Logger with a flat or partially charged battery will decrease the life of the battery 5.
