Calibrating the Meter (
CaL
)
To scale the meter without a signal source refer to Entering the K-Factor (
Factr
) on page 27 or Scaling
the Meter (
SCale
) on page 54.
The pulse input can be calibrated to display the process in engineering units by applying the appropriate
input signal and following the calibration procedure.
The use of a calibrated signal source is strongly recommended.
A calibrated input will work with Automatic Unit Conversions as described on page 34. The units for the
display values that must be entered are a combination of the programmed
Rate Unit
and the time unit
(
Time UNIT
) entered in the
Calibrate
menu.
For example, if the
Rate Unit
is gallons, and the time unit (
Time UNIT
) is seconds, the units for the
display values entered in the
Calibrate
menu are gallons/second.
The multi-point linearization feature (
nopts
) can be used to linearize the display for non-linear signals. For
instructions on how to utilize this feature, see Multi-Point Linearization (
nopts
), page 58.
For instructions on how to program numeric values see
Setting
Numeric Values, page 19.
1. Press the
Up
arrow button to scroll to the
Calibration
menu (
CAL
) and press
Enter
.
2. The meter displays
nopts
. For a linear signal, press
Up
arrow. For a non-linear signal, refer to Multi-Point Linearization
(
nopts
), page 58.
3. The meter displays
CAL UNITS
. Press
Enter
to select the input units/pulse. The menu will read
FuNiT
.
4. Use the
Up
arrow to select the time unit. If entering display values in units/second, press
Enter.
Otherwise, select the time
unit. Refer to Pulse Input Time Unit (Time UNIT) on page 58.
