C H EC K /C A LIB R A TIO N PROCEDURE
General
The following procedure is arranged so the Type 324
can be calibrated with the least interaction of adjust
ments and reconnection of equipment. A picture of the
test equipment required for each group of steps is given
to aid in identification of the necessary equipment. The
control settings and test equipment setup throughout
th is procedure continue from the preceding step(s)
unless noted otherwise. The control settings can be
checked at any test equipment required picture by set
ting the controls as given at the start of the procedure
under the heading Preliminary Control Settings. Then
make any changes listed beneath the test equipment
required picture under the heading Partial Procedure
(also applies to partial calibration procedure).
NOTE
Control titles which are printed on the outside of
the Type 324 are capitalized in this procedure (e.g.,
VOLTS/D/V). Internal adjustments are initial capi
talized only (e.g.. Limit Centering).
The following procedure uses the equipment listed
under Test Equipment Required. If other equipment is
substituted, control settings or calibration setup may
need to be altered to meet the requirements of the
equipment used. Detailed operating instructions for the
test equipment are not given in this procedure. Refer to
the instruction manual for the test equipment if more
information is required.
NOTE
This instrument should be calibrated at an ambient
temperature of +25°C ±5°C for best overall accur
acy. The performance of this instrument can be
checked at any temperature within the 0 °C to
+40°C range. If the ambient temperature is outside
the given range, see Section 1 for the applicable
tolerances.
