1.
Enter the menu „CALIB. ROUTINE“ by pushing
.
2.
The display shows: „ZERO ADJUSTM.“
Beginning with step 3, the automatic Time-out is not active.
3.
Push the
- button. Display: „000“ flashing. The Control Module adjusts the actual zero point.
Therefore this procedure must be performed in clean or synthetic air.
4.
„APPLY SPAN GAS“ tells you, that the zero point has been found and saved.
5.
Make sure you have the appropriate test gas on hand. Push the
-button. Display: „GAS“ - flashing.
Connect the test gas adapter and turn on the gas. The module starts searching a stable signal.
Make sure that sufficient test gas is available. If no test gas is applied or there is not
enough test gas for the adjustment in the cylinder, the module reports “ERROR 8”.
6.
„CALIB. FINISHED“ tells you that the signal is stable – a plateau has been found. Turn off the gas.
7.
Push the
- button.
8.
In case the display does not show the concentration of the gas cylinder, adjust it by pushing the
◄
- or
►
- button. Push and hold
◄
- or
►
for speed mode. Entering the concentration must be
carried out in the respective display unit, e.g. combustible gases are shown in % LEL. See the last
column of the program listing
.
Confirm with Enter.
9.
If needed you can enter a reference factor for the Statox 501 HRC, ARE and PID sensor heads.
Program it with the
◄
-
or
►
- button. If you need to correct your entry, push „Reset“. How to use
response factors is described in the relevant sensor head manual. If
no factor
needs to be
programmed, leave the value at
1.00
.
10.
Close the menu with Enter.
a)
Display:
„GAS CONC ERROR“
: (only possible if the response factor is not 1). This tells you that the
product (response factor * span gas concentration) is not within the permitted range for span
gas. Confirm with
. This brings you back into the main menu. Check the input for reference
factor and gas concentration and accordingly use a test gas with suitable concentration for
recalibration.
b)
Display:
„CALIBR. FAILED“
:
Calibration failed, because the calculated plateau signal is too low. Confirm with
-button. This
brings you back into the main menu. Check the values for response factor and gas concentration.
Repeat the calibration with a test gas with higher concentration or replace the sensor.
c)
Display
„DONE“:
The calibration was successful. After 2 s the display changes.
