Programming the Meter (PRoG)
It is very important to read the following information, before proceeding to program
the meter:
 There
is
no need to recalibrate
the meter for milliamps when first received
from the factory.
 The meter is factory calibrated for milliamps prior to shipment. The calibration
equipment is certified to NIST standards.
 Use the
Scale
menu to enter the default 2-point scaling without a signal source - or
 Use the
Calibrate
menu to apply a signal from a calibrator or a flowmeter for the
default 2-point scaling.
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
Multi-Point Linearization (lnear) menu selection prior to scaling and
calibration of the meter, see page 39 for details.
Additional parameters, not needed for most applications, are viewed and program-
med with the Advanced features menu, see Advanced Features Menu page 35.
