Users Manual

To use the Calibrator’s internal pump, refer to Figure 3 and

perform the following steps:

1. Depressurize the line before connecting the

Calibrator.

2. Connect the pressure transmitter under test to the

Calibrator internal sensor as shown in Figure 4 (for

internal pressure sensor measurements) or Figure 5

(for pressure module measurements.)

Note

To avoid leaks, use Teflon tape or similar sealant

on all pressure connections.

3. Make sure the pressure/vacuum switch on the

Calibrator is in the desired position. Forward

(clockwise) is for pressure; backward (counter-

clockwise) is for vacuum.

4. Turn the pressure/vacuum release control backward

(counter-clockwise) to vent pressure/vacuum from the

pump.

5. Press Zto zero the pressure display.

6. Turn the fine adjustment knob to mid-range.

7. Turn the pressure/vacuum release control forward

(clockwise) to close the release valve.

8. Work the pump handle in and out to apply

incrementally larger pressure/vacuum changes.

Shorten the stroke to apply smaller increments of

pressure/vacuum change.

9. To make very small pressure/vacuum changes, use

the fine adjustment knob.

Note

This knob adjusts a small internal reservoir to

vary the total volume. With larger external

pressure/vacuum volumes, this control will adjust

pressure or vacuum within a smaller range.

10. Depressurize the system before disconnecting the

pressure line.
