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.
