•
One or more rate channels: Channel A
(Ch-A), B (Ch-B), or C (Ch-C)
•
Toggle between rate channels: Ch-A &
Ch-B, Ch-A & Ch-C, Ch-B & Ch-C, and
Ch-A, Ch-B, & Ch-C
•
Total or grand total: Ch-A or Ch-B
•
Rate and total or grand total: Ch-A, Ch-B
•
Relay set points
•
Max/min values: Ch-A, Ch-B, or Ch-C
•
Toggle between any rate channel & units
•
Total and units: Ch-A or Ch-B
•
Toggle between totals: Ch-A & Ch-B;
Ch-A, Ch-B, and sum of Ch-A and Ch-B
•
Modbus input
Line 2 may also be set to show engineering
units or be off, with no display.
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 the process
are stored until reset by the user or until
power to the meter is turned off.
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 and
two prevent resetting the totals.
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.
Total: Prevents resetting the total manually
Gtotal: Prevents resetting the grand total
manually
