Programming the Meter (prog)
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
milliamps and volts depending on the input selection. The
calibration equipment is certified to NIST standards.
 Use the Scale menu to scale the process input (e.g. 4-20 mA). A
calibrated signal source is not needed to scale the meter.
 Use the Calibrate menu to apply a signal from a calibrator or a
flowmeter.
 The LI55 is a single input meter with dual-scale capability.
The Program menu contains the Scale and the Calibrate menus.
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 (
Linear)
menu selection prior to scaling and calibration of the meter, see page
81 for details.
If the dual-scale level feature is selected in the Setup menu, the Scale 1
and Scale 2 menus are enabled for PV1 & PV2 respectively.
The process input may be calibrated or scaled to any display value
within the range of the meter.

Additional parameters, not needed for most applications, are
programmed in the Advanced Features menu; see Advanced Features
Menu, page 75.
