7.1 Zero
Start the procedure by calibrating the zero pressure.
The display indicates “Cal. Zero”. Press up (4) and down
(3) to set the value nearest to 0. The most right value
(around 400) indicates the digital to analog value from
the controller. This is an indicator value and can be used
for error solving and service. When the displayed value
is set with up and down keys, press enter to store the
calibrated zero value into memory. The display will
shortly show “strd”. The zero now is calibrated.
Press (6) again
7.2 Span
The display now indicates “Cal. Span”. Start the pump.
Use the up (4) and down (3) button to match the reading
from the TVS against the calibrated vacuum meter. The
most right value indicates the digital to analog value
from the controller. This is an indicator value and can be
used for error solving and service. Press enter to store
the calibrated span value into memory. The display will
shortly show “strd”. The span is now calibrated.
Press (6) again.
7.3 Dimension
The display shows readout. Use the up (4) and down (3)
button to switch dimension to:
mmHg
mBar
hPa
PSI
Press enter to store the readout into memory.
Press (6) again
The display is in operation mode again.
7.4 Note
Pressing (6) without using “enter” (2) will not change the
calibration, so not using “enter” will not store the
changed values! Changing the dimension will not
change the zero or span as the vacuum readout is
calculated from the internal analog to digital converter
