1. Handling 1.1 General advice - For cleaning the instrument please do not use abrasive 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 instrument. Do not use force to connect the probe or interface plugs in. The interface plug is different from the probe plug. If no sensor is connected to the instrument while switching on „open“ shows on the display (Please refer to chapter error codes/troubleshooting).
1.4.1 Measuring unit switching °C, °F and Resistance (Ohm’s) Unit = Measuring unit Measuring unit temperature (°C=Celsius, F°=Fahrenheit, o=Ohm) To change the measuring unit push [ENTER/MENUE]. Use the up and down keys [] to select Unit. Push again [ENTER/MENUE]. On the right corner of the display appears °C, °F or o. Use the up and down keys [] again to adjust the requested measuring unit and push [ENTER/MENUE] to confirm. Push [ESC] to be back in the measuring mode.
.4.4 Calibration function / [CAL] Despite high quality manufacturing techniques, each probe is slightly different from specified standards. To eliminate inaccuracies caused by exchanging or ageing of probes, the instrument offer easy calibration functions which guarantee that the system accuracy is always as good as if the instrument was specifically calibrated to the individual probes in our laboratory. The instruments offer five different calibration options: 1) [OFF]:Standard characteristic curve (e.g.
3.) Calibration by physical standard references / oP2 Use the up and down keys [] to select oP2. Push [ENTER/MENUE] to confirm. On the bottom of the display appears 1 P. For changing between a 1-Point 1 P, 2Point 2 P or 3-Point 3 P - calibration use the up and down keys []. oP2 1P 2P 3P Example of a 1-Point calibration: Push [ENTER/MENUE] to confirm. On the display appears CALC. After the displayed measuring value is stabile push [ENTER/MENUE].
The CAL-segment and the small 4 indicates to the user that oP4 is activated. Note: If a Smart probe will be disconnected during the instrument is working the instrument automatically switch to the CAL-menu. 1.4.4 Channel activation (only 2-channel instruments) / [Chnl] Chnl = channel To activate or deactivate a measuring channel push [ENTER/MENUE]. Use the up and down keys [] to select Chnl. Push again [ENTER/MENUE].
E.g. of the instrument’s LCD by activated logging mode: On the bottom you can see the percentage of the occupied memory(0..99%). If a calibration option is activated the display is alternating between displaying memory status and calibration information. 1.5 Recalling the memory data (HOLD MAX MIN AVE) After pushing first time the key [HOLD MAX MIN AVE] the actual values will be held on the display. Pushing again the key [HOLD MAX MIN AVE], the saved maximum-, minimum and average values will be displayed.
The Instrument has a special Tare/Zero-button. Pressing the [F1] key once, the instrument will subtract the last measured value from the actual measured value. So if the measurement does not change zero appears on the instrument’s display. If you press the [F1] key once again the instrument move to the Normal-Mode. E.g. Display with activated Zero-Mode: The arrow on the left indicates that the instrument is working in the Zero-Mode [F1].
