Martel Electronics BetaGauge PIR PRO - Manual (Page 10)

RS-232 Interface
An RS-232 interface is standard on the BetaGauge PIR. Serial
communication can be used for configuration, calibration, and to
transfer measurement data from the gauge. For detailed
specifications on the interface and software communication, see
pages 14 and 15 in this manual.
WARNING
The RS-232 interface must not be used in hazardous areas.
7. Cleaning
To clean the BetaGauge PIR use a cloth with a mild cleaning
solution.
8. Specifications
All specifications cover the temperature range from 0°C to +50°C, unless
otherwise noted.
Available Input Ranges
See page 13 for a table of available ranges in PSI plus equivalent
ranges and resolution for all engineering units
Accuracy
Positive Pressure:: ±0.04% of reading ±0.01% of full scale
Vacuum: ±0.1% of the full scale vacuum measurement
(15 PSI or 1 Bar)
For gauges with full scale ranges equal to, or less than 100 psi
(2 BAR), vacuum operation is limited to -5psi (-350 mBar) except
for the compound range of -15 to 30 PSI (-1 to 2 Bar).
Over Pressure Protection:
See table of Ranges and Resolutions, page 13.
Temperature Compensation
0°C to +50°C (32°F to +122°F) to rated accuracy
Note: For temperatures from –10 °C to 0 °C and 50 °C to 55 °C add
.005% F.S./°C
