    1. Handling 1.1 General advice • For cleaning the instrument please do not use abra- sive cleaner but a dry or wet piece of cloth. • Please store the measuring instrument in a dry and clean place. • Avoid any force like shocks or pressure to the instru- ment.

  • Page 5: Menu

    Note: On all instruments you can select the measure- Important! ment category (chapter 1.4.2. Prob) according to the model version. Instruments that are delivered only with one probe the correct measurement category is preset. In other case please check chapter 1.4.2. (Prob) for the correct set-up.

  • Page 8: Calibration (Cal)

    The instruments offer three calibration options: 1) [OFF]:Standard characteristic curve (e.g. Pt100- resistance according DIN IEC 60751) 2) [OP1]:Calibration by code (2 x four digit code) is equivalent to a 2-point calibration The code is marked clearly by a label on each stan- dard probe.
  • Page 9 Display-indication with active calibration code (OP1): The CAL -segment and the small 1 on the left indicates to the user that oP1 is activated. Calibration by physical standard references / oP2 Use the up and down keys [ ] to select oP2. Push [ENTER/MENUE] to confirm.

  • Page 10: Calibration

    Display-indication with active calibration code (OP2): The CAL-segment and the small 2 on the left indicates to the user that oP2 is activated. 1.4.4.1 Calibration function of the combination probe (humidity/temperature) [CAL] Each humidity probe is a combination probe. That means that beside the humidity sensor these probes also contain a temperature sensor.

  • Page 11: Channel Activation (Chnl)

    Standard linearization / [oFF Use the up and down keys [ ] to select [oFF. Push [ENTER/MENUE] to confirm. Calibration by code / oP1 Use the up and down keys [ ] to select oP1. Push [ENTER/MENUE] to confirm the desired setting. On the bottom of the display a small 1 appears, after this number a four-digit number (Hex-Code /0..F) is dis- played.

  • Page 12: Memory Setup (Lo6)

    Push [ENTER/MENUE] and use the up and down keys ] to select ArEA. Push [ENTER/MENUE] to con- firm. On the left corner of the display appears a small 1, which indicates the selected channel. For changing the channel use the up and down keys [ ] .

    1.5 Recalling the memory data (HOLD MAX MIN AVE) After pushing first time the key [HOLD MAX MIN AVE] the actual value will be hold on the top display line (big display). Pushing again the key [HOLD MAX MIN AVE], the saved maximum-, minimum and average value will be displayed in the bottom display line (small display).

    o = Ohm (Pt100) H = Hertz (flow m/s) u = Micro volt (thermocouples) U = Volt (humidity) 1.8.2 Zero adjustment A long press on the F1 button (approx. 3 s) enables you to set the displayed value on 0. Before pressing the button make sure that the actual value also amounts to 0 (no current/pressure at the probe).

  • Page 15: Power Supply / Changing The Battery

    2. Power supply For the power supply of the instrument a 9 Volt dry bat- tery is used. To exchange the battery switch of the instrument and open the battery cover on the backside of the instrument. Remove and disconnect the battery from the instrument.
