Electrical to Pressure Test

You can perform an electrical to pressure calibration
test using either the conventional mode or the SYS
mode of operation. The following paragraphs describe
all of the possible configurations, as well as, the other
necessary equipment to perform an electrical to
pressure test.

Conventional Mode

You may perform this test if:

Your field instrument has an electrical input
range within the ability of the DC module on
the BetaGauge II, and

Your field instrument has a pressure output
range within the ability of the pressure module
on the BetaGauge II.
