4 Adjusting of the instrument
The cell correction may change due to natural ageing or deposits at the measuring cell. In case you have an accurate
reference liquid, you may adjust the instrument by changing the cell constant accordingly.
The temperature measuring is very stable and has to be adjusted in very seldom cases only.
To adjust the instruments according to Your needs proceed like follows::
•
Switch off instrument.
•
Switch
on
and press
hold-key during the segment test
( ), until the display shows the first parameter ‚CELL‘
•
If a parameter should be edited, press key up or down (
) , the setting of the parameter will be shown
and can be changed via up/down keys and receipt the changed parameter with
.
•
Jump to the next parameter with key

Adjustment of the measuring cells cell-constant
Offset of temperature
-2.0…2.0°C
-3.6…3.6°F
Offset setting of temperature measurement (see below)
Scale of temperature
-5.00…5.00%

adjustment of temperature measurement
Display = (measured value - offset) * ( 1 + scale adjustment/100)
Pressing
again stores the settings, the instruments restarts (segment test)
Please note:
If there is no key pressed within the menu mode within 60 seconds, the adjusting will be
cancelled, the entered settings are lost!
5 System Messages
Er. 1 = measuring range has been exceeded
-- =
Sensor Error
Er. 7 = System fault - the device has detected a system fault (defective or far outside allowable ambient
temperature range)
If
"BAT”
is displayed at the left side of display, the battery is weak, measuring can be continued for a short period.
If
“bAt”
is displayed in the main display the battery is used up and needs to be replaced. Measuring is no more
possible.
6 Inspection of the accuracy / Adjustment Services
Accuracy can be inspected with test-solutions (extra equipment).
If the precision is no more corresponding to the imprint of the GPAD 38, we suggest to send the device to the
manufacturer for a new adjustment.
