Calibrating the Meter with External
Source (
CAL-A
,
CAL-B
)
To scale the meter without a signal source, refer to
Scaling the Meter without a Signal Source (
The meter can be calibrated to display the process
variables in engineering units by applying the
appropriate input signal and following the calibration
procedure.
The use of a calibrated signal source is strongly
recommended to calibrate the meter.
Warm up the meter for at least 15 minutes before
performing calibration to ensure specified
accuracy.
Channel B is calibrated similarly to Channel A, shown
below.
Calibrating the Meter for Channel
A (
CAL-A
)
Note: The display values (
DiS 1
and
DiS 2
) need to
be in units of measure per second.
Note: Inputs for the above example are:
Input 1: 0.0 Hz; Display 1: 0.0 gallons/min
Input 2: 1000.0 Hz; Display 2: 6000.0 gallons/min
Total & Grand Total Setup (
tsetup
)
The time base and total and grand total conversion
factors for input channels A and B are located in the
Totalizer Setup
menu.
The time base is determined by the rate
programming. Enter the time unit of the programmed
rate scale.
For example: A rate display scaled in
engineering units of gallons per minute would use a
time base of minutes.
Total & grand total conversion factors for channel A
and B are programmed independently. This means
that one total or grand total can be displaying the
value in gallons while another displays in million
gallons, liters, m
3
, etc.
Total & Grand Total Reset (
treset
)
Total reset menus are located in the
Program
menu.
The totals can be programmed for manual or
automatic reset. In the automatic reset mode, a
programmable time delay (
t dly
) in seconds is
available to reset the total or grand total after the
assigned preset is reached.
