6. Push  and  to toggle the thermocouple display between °F and °C.
7. Push  and  to toggle the cold junction compensation between the internal
temperature sensor and an external reference.
8. Use the numeric keypad to type the necessary output value and push E.
9. As an alternative, use M or  to select a digit to change, followed by  or P to ramp
the digit up or down. This method gives you a simple solution when small changes to
an output value are necessary, or if is necessary to increment or decrement decades.
10. For best accuracy, it is recommended to zero the TC millivolt circuit daily, or if the
Product is used out of the ambient temperature range of 18 °C to 28 °C. This
procedure is given in the “Thermocouple (T/C) Measure” section of this chapter.
Pressure Measure
Many ranges and types of pressure modules are available from Fluke. The Product can
use the Fluke Model 700 Series Modules. Before you use a pressure module, read its
instruction sheet. Pressure modules vary in use, media, and accuracy.
1. Connect the pressure module to the Product as shown in Figure 2-7.

2. Push . The Product automatically senses which pressure module is attached and
sets its range accordingly.
3. Push  to select the necessary pressure units to show.
4. Before you attach the module to the pressure source, zero the module as given in the
instruction sheet that came with the module. Procedures can be different, but all use
 and .
5. Attach the module to the pressure source. Refer to the instruction sheet that came
with the module. Follow all safety precautions when you do work with high
pressures.
