RAW BRIDGE INPUT
Option
The Raw Bridge Input option lets you monitor the Wheatstone bridge
input signal (without offset correction) for troubleshooting purposes.
The acceptable range for this signal is -500 mV to +500 mV.
Note:
This signal also appears at test point E4 on the XMO2 printed
circuit board #703-1139.
The current Raw Bridge Input signal is displayed.
This completes the prompts for the Raw Bridge Input option, and the
XMO2 returns to the Test Inputs? menu.
OFFSET INPUT Option
The Offset Input option lets you monitor the XMO2 offset correction
signal. The acceptable range for this signal is 0 V to -4.000 V.
Note:
This signal also appears at test point E6 on the XMO2 printed
circuit board #703-1139.
The current Offset Input signal is displayed.
This completes the prompts for the Offset Input option, and the
XMO2 returns to the Test Inputs? menu.
