2.2 Current calibration
This procedure must only be done when using new sensors. You can find the sensor specific
current on the sensor label.
Push the “
Cal”
button
while “ICAL”
is active on the display.
Now the display shows the current of the sensor that has most recently been used. If the current
on the display is correct, confirm it by moving the switch to
“ON”,
or alter by pushing and
holding the
“Cal”
button.
2.3 Oxygen sensor
The calibration procedure is the same as above, but you can use fresh air as span gas. Fresh
air always contains 20,9 % oxygen. Zero can be adjusted with pure Nitrogen
(GCAL)
or
electronically
(ICAL)
.
3. Alarm thresholds
Compur Monitors recommends to strictly observe the local regulations for the alarm thresholds.
Open the instrument. Use proper safety measures for handling CMOS components.
Place switch in
“TEST”
position.
Following the normal self test which occurs when powering on, push button “A1”. The display
will now show the active alarm threshold and an arrow. To increase the threshold push and hold
“A1”. To decrease the threshold push and hold ”A2”. If the desired alarm threshold appears on
the display release the button and thus save the new value. Now move the switch into position
“ON”
.
Follow the same procedures for setting the alarm threshold for A2.
