Getting Acquainted with the Calibrator
Press
O
to turn the Calibrator on and off. The Calibrator
displays pressure and current measurements
simultaneously. See Figure 2.
The upper part of the display shows the applied pressure
or vacuum. (Vacuum is shown as a negative value.) Press
U
to select a different unit. When you cycle the power
off and on, the Calibrator retains the unit you last used.
The lower part of the display shows the current (up to 24
mA) applied to the current (mA) inputs. The current inputs
are fused with a 0.125 A, 250 V fast fuse (Littelfuse
type
2AG).
To source loop voltage, press
U while pressing O on.
Pushbutton operation is described in Table 4. Pump
features are shown in Figure 3 and described in Table 5.
