Setting the Display Units or
Custom Tags (
units
)
Use this menu to enter the unit or custom tag that will
be displayed if:
1. Alternating rate, total, or grand total and
units is selected in the
units
menu, or
2.
d unit
is selected as the line 2 parameter.
See the Setting the Display Parameter & Intensity
(
dsplay
) flow chart on page 40 to access the display
menu to show the unit or tag on line 2. The
engineering units or custom legends can be set using
the following 7-segment character set:

Notes:
1. Degree symbol represented by (<) if programming with
MeterView Pro.
2.
The letters “m” and “w” use two 7-segment LEDs each;
when selected the characters to the right are shifted one
position.
3. Press and hold up arrow to auto-scroll the characters in
the display.
Setting the Decimal Point (
dEc pt
)
The decimal point may be set with up to five decimal
places or with no decimal point at all. The rate, total,
and grand total decimal points are independent.
The decimal point selection should be made prior to
scaling, calibrating or programming the meter.
Pressing the right arrow moves the decimal point one
place to the right until no decimal point is displayed,
then it moves to the leftmost position.
Pressing the up arrow moves the decimal point to the
left.
Programming the Rate/Totalizer
(
prog
)
The meter may either be scaled (
SCALE
) without
applying an input, calibrated (
Cal
) by applying an
input, or you may use the K-Factor menu to match the
rate/totalizer with a flowmeter’s k-factor (pulse/unit of
measure). The meter comes factory calibrated to
NIST standards, so for initial setup, it is
recommended to use the (
SCALE
) function.
The Program menu contains the following menus:
1. K-Factor calibration
2. Scale without a signal source
3. Calibrate with a calibrated signal source
4. Total time base & conversion factor
5. Grand total time base & conversion factor
6. Total reset mode for total & grand total
The pulse inputs may be calibrated or scaled to any
display value within the range of the meter.
Note: The Scale , Calibrate , and K-Factor functions are
exclusive of each other. The meter uses the last function
programmed. Only one of these methods can be employed
at a time. The Scale and Calibrate functions can use up to
32 points (default is 2). The number of points should be set
in the Advanced menu prior to scaling and calibration of the
meter. See Multi-Point Linearization (
Linear)
menu on
page 52 for details.
Additional parameters, not needed for most
applications, are programmed in the
Advanced
Features menu. See Advanced Features Menu on
page 50 .
