6. Commissioning, operation

There are four types of resistance thermometers: "P100-385", "P100-392",

"P100-JIS" and "CUSTOM". With "CUSTOM", custom resistance thermometers

can be selected. Use the "SELECT" option to select the desired probe type and the

"DONE" option to store the change and return home.

The default resistance thermometer type is "P100-385" (Pt100-385).

6.4.7 Damping

Damping can be turned ON or OFF using the "DAMPING" menu selection. As soon as

the damping function is switched ON, the calibrator displays the running average of the

last ten measurements. The calibrator makes approximately three readings per second.

6.4.8 Pump limit

To prevent overpressuring for sensitive test items, a maximum pressure (pump limit) can

be set. In this mode, use the arrow keys to set the maximum pressure.

6.4.9 HART™ Resistor

An internal 250 Ω HART™ resistor can be enabled when the calibrator is operated

in the "mA measure-24V" mode. This allows a HART Communicator to be connected

across the mA terminals and eliminates the need for adding an external resistor.

When the HART™ resistor is enabled, the maximum load driving

capability is 750 Ω.
