Setting the Input Calibration (InCal)
It is very important to read the following information, before proceeding
to program the meter:
•
The meter is factory calibrated prior to shipment to read in amps
and volts. The calibration equipment is certified to NIST standards.
•
Use the Scale menu to scale the current and voltage inputs. A
calibrated signal source is not needed to scale the meter.
•
Use the Calibrate menu to apply a signal from a calibrator or other
live signal source.
The Program menu contains the Scale and the Calibrate menus for
channels A & V.
The process inputs may be calibrated or scaled to any display value
within the range of the meter.
Note: The Scale and Calibrate functions are exclusive of each other.
The meter uses the last function programmed. Only one of these
methods can be employed at a time. The Scale and Calibrate functions
can use up to 32 points (default is 2). The number of points should be
set in the Advanced Menu under the menu selection prior to scaling and
calibration of the meter, see page 71 for details.
