Model PD6300 Pulse Input Rate/Totalizer Instruction Manual
40
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.
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
)
It is very important that one reads the following information before
programming the meter:
•
The meter has been factory calibrated to read input frequency in Hz
(pulses/sec). The calibration equipment is certified to NIST
standards.
•
Use the K-Factor menu to match the rate/totalizer with a flowmeter’s
k-factor (pulse/unit of measure).
•
Or use the Scale menu to scale the pulse input (pulse/sec) without a
signal source.
•
Or use Cal menu to calibrate the rate/totalizer using a signal source.
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
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 under the Multi-Point Linearization
(
Linear
)
menu selection prior to scaling and calibration of the meter, see page 74
for details.
The pulse inputs may be calibrated or scaled to any display value within
the range of the meter.
