9. Offset- and slope-adjustment
The offset and slope-adjustment function can be used for compensating the tolerance of the used probes.
Please note: The settings of the offset- / slope-adjustment will be cancelled, when no button was pressed
for more than 60 sec. Changes you may have made already won‘t be saved and will be lost!
Hint:
The buttons 2 and 3 are featured with a ‘roll-function‘. When pressing the button once the value will be raised
(button 2) by one or lowered (button 3) by one. When holding the button pressed for longer than 1 sec. the
value starts counting up or down, the counting speed will be raised after a short period of time.
The device also features a ‘overflow-function‘, when reaching the upper limit the device switches to the lower
limit, vice versa.

- Turn on the device and wait after it finished its built-in segment test.
- Press button 3 > 2 sec.
The device will be displaying “OFS.1“ (offset of input 1).
- Use button 2 and button 3 for setting the desired zero point offset-value.
The input of the offset will be in digits.
The value that had been set will be subtracted from the measured value of input 1.
The value that had been set will be subtracted from the measured value of input 1.
- Press button 1 to validate your selection. The display shows “OFS.1“ again.
- When pressing button 1 again, the device will be displaying “SCA.1“. (scale 1 = slope of input 1)
- Use button 2 and button 3 to select the desired slope-adjustment.
The slope adjustment will be entered in %. The value displayed can be calculated like this:
Displayed value 1 = (measured value input 1 – zero point offset 1) * (1 + slope adjustment 1 [% / 100]).
Example: The setting is 2.00 => the slope has risen 2.00% => slope = 102%.
When measuring a value of 1000 (without slope-adjustment) the device would display 1020 (with slope
adjustment of 102%)
adjustment of 102%)
- Press button 1 to validate the selection of the slope-adjustment. The display shows “SCA.1“ again.
- When pressing button 1 again, the device will be displaying “OFS.2“. (offset of input 2)
- Use button 2 and button 3 for setting the desired zero point offset-value.

- Press button 1 to validate the selection of the slope-adjustment. The display shows “SCA.2“ again.
Now you finished configuring the device’s offset and slope adjustment. Press button 1 to switch over to dis-

Example for offset- and slope-adjustment:
Example: Connecting a temperature probe (offset deviation depending on using long wires between probe and device)
The device displays the following values (without offset- or slope-adjustment): at 0°C = 2°C, at 100°C = 102°C
Therefore you calculated: zero point: 2
The device displays the following values (without offset- or slope-adjustment): at 0°C = 2°C, at 100°C = 102°C
Therefore you calculated: zero point: 2
slope:
102 – 2 = 100 (=>deviation = 0)
You have to set:
