9 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 cells
scale correction 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 the instrument and press hold-key (
)
during the segment test
(
)
until
the dis
play shows the first parameter “P_oF”
If a parameter should be edited, press key up or down (
), the setting of the
parameter will be shown.
You can be changed via up/down keys and receipt the changed parameter with
.
Jump to the next parameter with key

Scale 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 2 minutes, the
adjusting will be cancelled, the entered settings are lost!
10 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)
Er. 9 = Cable break - please return the device to the manufacturer
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.
11 Inspection of the accuracy / Adjustment Services
Accuracy can be inspected with test-solutions (extra equipment).
If the precision is not more within the admissible range, we suggest to send the device to the
manufacturer for a new adjustment.
It is also possible to order a
factory calibration certificate.
