EQUIPMENT PREPARATION
For the best overall accuracy and performance, this instru-
ment should be calibrated in an ambient temperature of
25°C ± 5°C.
Remove the instrument cabinet as described in the Cabinet
Removal instructions in the Maintenance section.
Turn the instrument on and allow at least a 10 minute
warmup time before proceeding. If the instrument is
operating on batteries and is stabilized at the ambient tem-
perature, no more than a 10 second warm up period is
required.
If the batteries are not fully charged, connect the instru-
ment to the correct power line voltage for approximately
1 hour before continuing with calibration. Leave the in-
strument connected to the power line during calibration
unless the batteries are fully charged.

WARNING
I
Potentially dangerous high voltages, which create
a possible shock hazard, exist inside this instru-
ment when it is operating with the cabinet re-
moved. Do not remove protective shields unless
the instrument is turned off and the power plug
is removed from the power line.
