or cursor key to ramp the digit up or down. This method offers a simple
solution when small changes to an output value are required, or if specific decades
need to be incremented or decremented.
i) For best accuracy, it is advisable to zero the T/C millivolt circuit daily, or if the 3001 is
being used outside of the ambient temperature range of 18 to 28 °C. This procedure
is described in section 4.7 on thermocouple measurements.
4.9 Pressure Measure
The 3001 can support the following types of pressure modules:
• BETA Calibrators Corporation BETA Port-P Modules
• Fluke Corporation Model 700 Series Modules
• Mensor Corporation Model 6100 Modules
The BETA modules require the use of the BETA BPPA-100 Adapter and offer the best
performance vs. cost. The adapter allows the user to "Hot Swap" a pressure module for
quick range changes. For applications that require very high accuracy the Mensor 6100
Series, while expensive, will yield the best accuracy. Pressure modules from Fluke will
plug directly into the 3001. It may be helpful to discuss your pressure needs with Martel
Technical Support before you purchase modules.
a) Connect the pressure module to the 3001 as shown in figure 16.
Figure 16 - Pressure Module Connection
b) Press the key. The 3001 automatically senses which pressure module is
attached and sets its range accordingly.
c) Press the key to select the desired pressure units for display.
d) Before attaching the module to the pressure source, zero the module as described in
the instruction sheet that came with the module. Procedures vary, but all end with
pressing the and keys.
e) Attach the module to the pressure source according to the instruction sheet that
came with the module, taking care to follow all safety precautions when dealing with
high pressures.
