LI25 Series Loop-Powered Meters
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 scale parameters without applying a
live signal.
•
Alternatively, use the Calibrate menu to apply a signal from a
calibrator or a 4-20 mA transmitter to calibrate the meter.
The Program menu contains the Calibrate and the Scale menus.
Inputs may be calibrated or scaled to any display within the range of the
meter.

Additional parameters, not needed for most applications, are
programmed with the Advanced features menu, see Advanced Features
Menu, page 25.
Error Message (Error)
An error message indicates that the calibration or scaling process was
not successful.
After the error message is displayed, the meter reverts to input 1,
allowing the appropriate input signals to be applied.
The error message might be caused by one of the following conditions:
1.
Minimum input span requirements not maintained.
2.
Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum input span is the minimum difference between input 1 and
input 2 signals required to complete the calibration or scaling of the
meter. The minimum span is 0.40 mA.
