Do not use the ProcessMeter if it looks damaged.
Examine the ProcessMeter before use. Look for cracks in the case,
missing plastic, or damaged insulation around the connectors.
Inspect the test leads for damaged insulation or exposed metal.
Check for test lead continuity. Replace damaged test leads.
Do not use the ProcessMeter if it operates abnormally. Protection
provided by the ProcessMeter may be impaired. When in doubt,
have the ProcessMeter serviced.
Do not apply more than the rated voltage as marked on the
ProcessMeter between terminals or between any terminal and
earth ground.
When using probes, keep fingers behind the finger guards on the
probes.
Use caution when working above 30 V ac rms, 42 V ac peak, or
60 V dc. Such voltages pose a shock hazard.
Connect the common lead (COM) before connecting the live test
lead. When disconnecting test leads, disconnect the live test lead
first.
Remove test leads from the ProcessMeter before opening the
battery compartment door.
Do not operate the ProcessMeter around explosive gas, vapor, or
dust.
During normal operation, use only type AA batteries, properly
installed in the ProcessMeter case, to power the ProcessMeter.
Make sure the battery compartment door is closed and latched
before you operate the ProcessMeter.
During calibration adjustment, use only specified calibration
equipment listed in Table 2.
When servicing the ProcessMeter, use only specified replacement
parts.
Before measuring current, check the ProcessMeter's fuses, see
"Checking and Replacing the Fuses" .
To avoid false readings, which can lead to possible electric shock
or personal injury, replace the batteries as soon as the low battery
M
indicator ( ) appears.
