NOSHOK 1800 Series Attachable Loop-Powered Indicator - Manual (Page 13)

- Press button 1 to validate your selection. The display shows “ OFFS“ again.
- When pressing button 1 again, the device will display “ SCAL“ (scale = slope).
- 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:
Display = (measured value – offset – di.Lo) * (1 + slope adjustment [% / 100] ) + di.Lo
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%)
- Press button 1 to validate the selection of the slope-adjustment. The display shows “ SCAL“
again.
Now you finished the offset and slope adjustment of your device.
Press button 1 to finish the adjustment and to switch over to display the measuring value.
Examples for offset- and slope-adjustment
Example: Connecting of a pressure-transducer
The device displays the following values (without offset- or slope-adjustment): 0.08 at 0.00 bar
and 20.02 at 20.00 bar.
Therefore you calculated: zero point: 0.08
slope: 20.02 – 0.08 = 19.94
deviation: 0.06 (= target-slope – actual-slope = 20.00 - 19.94)
You have to set: offset = 0.08 (= zero point-deviation)
scale = 0.30 (= deviation / actual-slope = 0.06 / 19.94 =
0.0030 = 0.30%)
7 Min-/max-value storage
The device features a minimum/maximum-value storage. In this storage the highest and lowest
performance data is saved.
Calling of the minimum-value press button 3 shortly
the device will display “Lo“
briefly, after that the min-value
is displayed for about 2 sec.
Calling of the maximum-value press button 2 shortly the device will display “Hi“
briefly, after that the max-value
is displayed for about 2 sec.
Erasing of the min/max values press button 2 and 3 for 2 sec. the device will display “CLr“
briefly, after that the min/max-
values are set to the current
displayed value.
