1. Congratulations! In the seca 242/seca 245 electronic measuring rod, you have acquired a highly accurate and simultaneously sturdy piece of equipment. seca has been putting its experience at the service of health for over 150 years and as market leader in many countries of the world, is always setting new standards with its innovative developments in weighing and measuring. seca 242/seca 245 measuring rods are used for diagnosis and treatment in hospitals and doctors surgeries. The display unit is separate from the slide unit. The value determined is transmitted by radio. Power is provided exclusively by batteries and there are no annoying cables. 2. Safety The seca 242 measuring rod is fixed directly to the wall you can define the height at which it is fixed, and thus the measuring range, yourself. The seca 245 measuring rod is supplied with a statometer. This can be moved on castors, allowing it to be used on a mobile basis. The height displayed can be switched between centimetres (cm) and inches (ins). On both models, the current value can be specified as a temporary zero point, allowing relative measurements of extremities, for example, to be made. The measuring rod is of a very sturdy construction, and will give you long and reliable service. Before using the new measuring rod, please take a little time to read the following safety instructions. Follow the instructions in the instruction seca 245 only: ensure that the patient manual. does not lean against the measuring rod You must not drop the measuring rod or risk of falling! display housing nor subject them to violent shocks. thorised persons.

4. Operation Controls and displays Calibration (seca 242 only) Calibration is required only if the bottom end of the measuring rod is not exactly on the standing surface. The drill may have slipped during mounting or you may deliberately have selected a different fixing height to vary the measuring range. Calibration need only be performed once. Keep the ZERO key depressed and then switch on the display housing by pressing the START key. A flashing number appears this is the calibration counter. Release the ZERO key and then press it again for at least 1.5 seconds. Put a metre stick or other known measure underneath the head stop. Compare the value displayed with the actual value. They should match. 22
In order to change the value displayed so that it agrees with the actual value, proceed as follows: press the cm/ins key to increase the value in 0.5 mm increments. If you also press the ZERO key, the value changes rapidly. Press the ZERO key to reduce the value in 0.5 mm increments. If you also press the cm/ins key, the value changes rapidly. Complete the calibration process by keeping the ZERO key depressed for at least 5 seconds. The internal calibration counter is increased by 1. The measuring rod switches off. Measuring height Press the START key on the display housing. ----- is displayed initially. The last unit selected before the rod was switched off is active and marked with an arrow. If necessary, switch the unit in which height is measured (see page 24). Push the head stop far enough up the rod so that the person to be measured can stand underneath it comfortably. Ask the person to be measured to stand with his or her back to the measuring rod. Heels should be against the plate and the back and head straight. Now slide the head stop down until it touches the head. Read off the height measured on the display unit. For information on transferring the result to a connected scale, see page 26. Model 242/245 GB 23
Switching unit of height The display can be switched between centimetres (cm) and inches (ins). Switch on the measuring rod. Display will initially be in the last setting selected. To switch the display, press the cm/ins key. An arrow lights up next to the cm or ins display. Relative measurements The measuring rod can be set to zero at any desired position. This function allows relative measurements to be made and is used when measuring extremities, for example. Press the ZERO key to zero the measuring rod at the current position. ZERO SET is marked in the display. All lengths are now measured relative to this new zero point. If the zero point is not reached, the measured values shown are preceded by a minus sign. Press the ZERO key again when you want to display absolute length once more. 24
Switching off the measuring rod To switch off the measuring rod, press the START key again. If the measuring rod is no longer being used, it switches off automatically after 5 minutes. After measuring, push the head stop back up to prevent injuries occurring. Selecting a channel if you have two measuring rods To operate two measuring rods simultaneously in the same reception area, the channel for radio transmission on the display unit and the slide unit can be switched. For transmission to function, the channels on the display unit and the slide unit must match. Channel B is always selected when the measuring rod is delivered. To switch the channel, proceed as follows: Move the slide unit. Keep the DATA VALID key depressed for at least 5 seconds. The module is switched to the other channel. Keep the cm/ins key on the display unit depressed and switch it on. The channel of the display unit is switched. The active channel is displayed for 2 seconds (e.g. CH B). Note: it may be necessary to re-set the channel after the batteries in the slide unit have been changed. Your measuring rod is mobile (seca 245 only) It has two castors at the back. For mobile use, the seca 245 can be tilted slightly backwards and then moved on its castors. Model 242/245 GB 25
Connecting to a scale There is a serial interface in the display housing which allows the measuring rod to be connected to a scale. The scale is then able to add information about height and weight to other characteristic data. The interface cable required is available as an accessory. Use the interface cable to connect the scale to the RS 232 interface on the underside of the display housing. The current value is transmitted to the scale when the DATA VALID key on the display housing or on the head stop is pressed. Detailed information can be obtained from seca Customer Service. 5. Cleaning and care Clean the measuring rod and the outside of the display housing as required using a domestic cleaning agent or commercially-available disinfectant. Follow the manufacturer s instructions. Under no circumstances use abrasive or acid cleaners, spirit, benzene or the like for cleaning. Such substances can damage the high-quality surfaces and coding. 6. What do I do if... no display appears? Is the display housing switched on?
