PROGRAMMING METER K-FACTOR
Your SCAMP circuit board has been factory calibrated to include a four-digit k-Factor for
your specific meter (only if SCAMP is sold separately, i.e., without a meter,
is calibration
data not entered at the factory). The k-Factor is a number represented by the ratio of
pulse edges into SCAMP (from the pulser) and whole pulses per channel out of SCAMP
(to the electronic counter). The value of the k-Factor is a number in the range of 4.000
to 9999.
IMPORTANT: PERFORM THESE OPERATIONS BEFORE PROCEEDING!
Before beginning any programming, move the “LOCK” jumper located on the right-hand
side of the circuit board to the left-most position to unlock the unit. Also, move the
jumper marked “0/1” to the “0” position. NOTE: Care should be taken when the unit is
unlocked because factory loaded data can be lost or altered if the Data Entry pushbutton
switch is inadvertently depressed.
STEP 4A. Checking the Factory Programmed k-Factor
♦ Set the Function Switch located on the lower right-hand side of the SCAMP circuit
board to the “0” position. Observe the k-Factor value scrolling on the LED display.
The scrolling value will be a number such as “F19.58”. Confirm that the number
appearing on SCAMP is identical to the k-Factor listed on your Meter Calibration
Sheet.
If the k-Factor is correctly entered in SCAMP, you may proceed to the next
page “Computing and Programming Multi-Point Calibration Data”. If no data is
present, an “F0” will scroll across the LED display and you should proceed to Step
4B.
STEP 4B. Programming a New k-Factor in the Field
If required, a new k-Factor is easily programmed into SCAMP. Refer to your Meter
Calibration Sheet for a factory-determined value, or to Appendix C for a detailed
discussion on the calculation of
a new k-Factor for your meter. Then, return to this step
for loading the value into memory.
♦ Set the Function Switch located on the SCAMP circuit board to the “0” position.
♦ Set the Data Switches located along the top edge of the SCAMP circuit board to the
appropriate values to represent the four digit k-Factor for your meter, starting with
the left-most switch (sw5). The right-most switch (sw1) is reserved for an extra digit
to establish positioning (left-shifting) of the decimal point. For example, a k-Factor of
19.58 would be entered as 19582, where the last digit (“2”) specifies the positioning
of the decimal point, i.e., two places to the left. The range of valid entries is 4.000 to
9999.
♦ Depress the Data Entry Pushbutton located on SCAMP to enter the new k-Factor
value into memory. The LED display will now scroll the new value to verify that it has
been successfully loaded into memory.
