b. Turn on manometer and allow to self calibrate. Do not move
manometer while self-calibrating.
c. After zeroing the digital manometer, connect the “+” side of the
manometer to the Delta-P + port on the rear panel.
d. Connect the “–” side of the manometer to the Delta-P – port on
the rear panel.
e. Open both Delta-P + and – toggle valves to open flow through
the manometer.
f. Cal Flow Pres Span by entering the actual value read by the
manometer.
g. Press to save value.
h. Turn off the manometer; this meter does not have an automatic
turn off feature.
3. Return to the Pres/Vacuum Calibration, choose Vac/Flow > Vac Pres
Span . Calibrate the vacuum pressure span according to the following:
a. Use an acceptable vacuum manometer. If using a blue Druck
manometer, place blue manometer on bench.
b. Turn on manometer and let manometer self calibrate. Do not
move manometer while self-calibrating.
c. Connect the “+” side of the manometer to the Delta-P + port on
the rear panel.
d. Open Delta-P + toggle vales to open flow through the manometer.
e. Cal Vac Pressure Span by entering the actual value from the
reference manometer.
f. Press to save value.
The analog outputs should be tested if the concentration value on the front
panel display disagrees with the analog outputs. To check the analog
outputs, connect a meter to an analog output channel (voltage or current)
and compare the meter reading with the output value set on the Test
Analog Outputs screen.
Equipment Required:
Multimeter
Use the following procedure to test the analog outputs.
