Operational Considerations
The Model 9250-05 is highly resistant to most of the industrial environments that can cause
problems with resistance test equipment. The operating temperature of the Model 9250-05 is 32ºF
to 122ºF [0ºC to 50ºC]. Operations outside this range should be avoided. Temperature
compensation for resistance readings is detailed in the TC Option section (if applicable).
NOTE:
If any welding is to be performed near the Model 9250-05, or
anywhere on the process line where the Model 9250-05 is installed,
disconnect ALL cables from the Model 9250-05. This prevents system
overload by the current generated from welding.

Power Switch
A lighted push-button power switch is located on the front panel of the Model 9250-05. This
switch is the master power switch for the unit. If this switch is pushed in, the green LED lamp
should light. If the lamp does not illuminate, check the power line cord connections to ensure that
the unit has power. If the unit does have power and the lamp will still not illuminate, contact Harris
Instrument Corporation IRT Service for more information.
