3-3 Basic Operations
Selecting Pre-Programmed Display
Units
The BetaGauge II allows you to use pre-programmed
display units for calibrating your field instrument. For
each module installed, the BetaGauge II allows you to
select the units used to display data on the LCD. The
following paragraphs describe how to select display
units for both types of modules (BetaPort–DC and
BetaPort–P pressure).
BetaPort–DC Module
The BetaPort– DC module can measure in milliamps or
Volts. Upon initialization, the BetaPort–DC module
defaults to milliamp measurement.
Use the following procedure to specify a voltage
measurement:
1. Press CH 1 or CH 2, as appropriate, to select the
BetaPort–DC module for modification.
2. Press the function key corresponding to V/mA.
This function key is a toggle that alternates
between Volts and milliamps. You can view the
current selection in the LCD display for the
appropriate channel.
NOTE: The BetaPort– DC module is auto-ranging and
automatically selects the most appropriate
range for the measured value. Refer to
Appendix B, Specifications, for complete
range information.
