Checking the measuring range (span)
If the key is pressed five times,
∆
p100,
which is the value for the maximum differen-
tial pressure, appears in the display.
First check zero, as described in section
6.3.
Press key five times,
Readout:
∆
p 100 = X.XXX ( x1000 ) mbar.
Use a precision regulator to apply a test
pressure corresponding to the maximum
differential pressure
∆
p 100 while moni-
toring the pressure gauge.
Set point values:
∆
p = 0 mbar = 4 mA
(See also note on gas column correction on p. 17)
∆
p 100 = XXXX mbar = 20 mA
If the readout and output signal do not
correspond with the indicated value
∆
p100,
the upper range value of the measuring
range (span) must be calibrated.
Calibrating the measuring range (span)
First check zero, as described in section
6.3.
Turn write protection (switch 4) and span
protection (switch 3) OFF.
Press key five times.
Readout:
∆
p 100 = X.XXX ( x1000 ) mbar.
Use a precision regulator to apply a test
pressure corresponding to the maximum

toring the pressure gauge.
Keep key pressed down, the current
measured value is shown in the display.
Current signal I shows the present mA
value.
Press key, the span is calibrated,
current signal goes to 20 mA.

LED starts to flash rapidly.
Press key, the span is calibrated,
current signal goes to 20 mA,
The LED flashes continuously for ~ 2 s.
Release key, the LED goes out.
