Fluke 726 [59/80] Calibrating an i p device

Multifunction Process Calibrator

Calibrating an I/P Device

The following steps explain how to calibrate a device that

controls pressure. Proceed as follows:

1. Connect the test leads to the instrument under test as

shown in Figure 22. The connections simulate a

current-to-pressure transmitter and measures the

corresponding output pressure.

2. Press

A (upper display).

3. Press V for sourcing current (lower display).

4. If necessary, press

M for SOURCE mode.

5. Enter the desired current by pressing

X and W.

Press

Y and Z to select different digits.
