• Turn off circuit power before connecting the Product’s mA and COM terminals to a circuit. Place the Product in series with the circuit.

• When using a pressure module, make sure the pressure line is shut off and depressurized before disconnecting it from the pressure module.

Caution To avoid possible damage to the Product or to equipment under test:

• Disconnect the power and discharge all high-voltage capacitors before testing resistance or continuity.

• The Product’s MEASURE/SOURCE terminals are ESD (electro-static discharge) sensitive to levels above ± 4 kV. The Product can experience temporary loss of measurement or source functionality, which may require operator intervention to restore product function, or even cause permanent damage. In general, a disruptive ESD event will only occur during connection of the test leads to the circuits being measured or if the operator is carrying a large static charge and touches the Calibrator terminals. The most common cause of ESD is the user carrying the Product across a carpet, or other similar triboelectric activity, before they connection to the circuit being measured.

Caution To avoid mechanically damaging the pressure module:

• Never apply more than 10 ft.-lb. (13.5 Nm) of torque between the pressure module fittings, or between the fittings and the body of the module. Always apply appropriate torque between the pressure module fitting and connecting fittings or adapters.

• Never apply pressure above the rated maximum printed on the pressure module.

• Only use the pressure module with specified materials. Refer to the printing on the pressure module or the pressure module instruction sheet for the acceptable material compatibility.

1. Connect a pressure module to the Product as shown in Figure 13. The threads on the pressure modules accept standard ¼ NPT pipe fittings. Use the supplied ¼ NPT to ¼ ISO adapter if necessary.

2. Push either or . The Product automatically senses which pressure module is attached and sets its range accordingly.

3. Zero the pressure module as described in the module’s Instruction Sheet. Modules vary in zeroing procedures depending on module type, but all require pushing for 3 seconds.

Continue pushing to change pressure display units to psi, mmHg, inHg, cmH2O@4 °C, cmH2O@20 °C, inH2O@4 °C, inH2O@20 °C, inH2O@60 °F, mbar, bar, kg/cm2, or kPa.

Zeroing with Absolute Pressure Modules

To zero, adjust the Product to read a known pressure. This can be barometric pressure, if it is accurately known, for all but the 750PA3 module. The maximum range of 750PA3 is 5 psi; therefore the reference pressure must be applied with a vacuum pump. An accurate pressure standard can also apply a pressure within range for any absolute pressure module. To adjust the Product reading, proceed as follows:

1. Push , REF Adjust appears to the right of the pressure reading.

2. Use to increase or to decrease the Product reading to equal the reference pressure.

3. Push again to exit the zeroing procedure.

The Product stores and automatically reuses the zero offset correction for one absolute-pressure module so that the module is not rezeroed every time you use it.
