F
Field Calibration
G < fmt> <opt>
Start or resume the sensor operation: if needed, heat the ASIC, setup the sensor,
and output data on serial port; this restores default settings (refer to the FORMAT
and OPTIONS section).
H <low> <high>
Set the hydrogen reporting range: <low> to <high> in %H2.
I <low> <high> <err>
<not rdy>
Set the DAC current output range: <low> to <high>; error output <err>; and not
ready output <not rdy> milliamps. Possible range from 0 to 20 milliamps.
L < fmt> <opt>
Print current hydrogen reading. Used to poll for hydrogen readings. Default
format <fmt> is current setting (refer to the FORMAT <fmt> and OPTIONS <opt>
sections).
P <atm>
Select atmospheric pressure of gas.
Factory default pressure is 1 ATM.
S
Stop the sensor: turn off heater, set Bias to zero, set DAC outputs to zero, and
stop reporting data on the serial output.
V <low> <high>
<err> <not rdy>
Set the DAC voltage output range: <low> to <high>; error output <err>; and not
ready output <not rdy> in volts. Possible range from 0 to 5 volts.
X
Clear field calibration data (returns to last factory calibration data).
