Assignment
Display Line 1:
Channels A (Ch-A, current), V (Ch-V,
voltage), or P (Ch-P, apparent power);
toggle between (Ch-A & Ch-V, Ch-A & Ch-
P, Ch-V & Ch-P, and Ch-A, Ch-V, & Ch-P);
set points; max and/or min values for Ch-A,
Ch-V, or Ch-P; CH-A and units; Ch-V and
units; Ch-P and units, Modbus input, and
more.
Display Line 2:
Same as Display Line 1; plus units, tag or
turned off.
Programming
Methods
Four programming buttons, digital inputs,
PC and MeterView Pro software, or
Modbus registers.
Noise Filter
Programmable from 2 to 199
(0 will disable filter)
Filter Bypass
Programmable from 0.1 to 99.9% of
calibrated span
Recalibration
All ranges are calibrated at the factory.
Recalibration is recommended at least
every 12 months.
Max/Min
Display
Max/min readings reached by each
displayed input type are stored until reset
by the user or until power to the meter is
cycled.
Rounding
Select 1, 2, 5, 10, 20, 50, or 100
(e.g. rounding = 10, value = 123.45,
display = 123.50).
Password
Three programmable passwords restrict
modification of programmed settings.
Pass 1: Allows use of function keys and
digital inputs
Pass 2: Allows use of function keys, digital
inputs and editing set/reset points
Pass 3: Restricts all programming, function
keys, and digital inputs.
Non-Volatile
Memory
All programmed settings are stored in non-
volatile memory for a minimum of ten years
if power is lost.
