Model HF-15B High Frequency Spark Tester
HF-15B Instruction Manual – Page 47
3. Insert the BNC plug on the black wire into the “VOLTMETER
OUTPUT” terminal on the HF-CAL, and connect the dual banana plug
to the HF-CAL meter. Be sure the ground tab on the dual banana plug
is in the correct orientation.
Taking Calibration Readings
4. Turn on the HF-CAL meter to the Volts AC positions (V~).
5. Turn on the HF-15B and adjust the spark tester voltage to 3.00KV.
Record the voltage reading on the HF-CAL meter. Multiply this
reading by 100 to get the actual high voltage reading and record.
Repeat this step for all required test voltages.
6. If the readings are within tolerance, turn off the spark tester and
disconnect the HF-CAL
If the readings are not within tolerance, continue to the next section entitled
“Adjusting the Calibration” for adjustments.
Adjusting the Calibration
Entering the Calibration Mode
1. Press and hold the Down Arrow Button and the CR Button for
approximately 4 seconds. The spark tester will enter the configuration
mode and disable the high voltage output.
2. If the display is locked you will need to unlock the display with the PIN.
See “RC Security” section for more information.
3. Press the Down Arrow until “MCAL” is displayed on the voltage display.
Adjusting the Spark Tester Output voltage
4. Press the “B” button for several seconds until “VOUT” is displayed on
the voltage display.
7. Press the “R” button. The Fault Count display should show “S.00.0” representing
the set point value.
8. Using the UP/DOWN arrows adjust the output voltage up so that the Fault
Count display shows “S.01.0” for 1kV.
9. Check the actual output voltage on the meter from the HF-CAL, if this value is
not within the rated specification for the HF-15B Press the “CR” button. The
Fault Count display will change to “*.01.0”.
10. Using the UP/DOWN arrows adjust the reading on the meter from the HF-CAL
until the reading is within the rated tolerance for the HF-15B or as close to the
value on the Fault count display.
11. Once the meter from the HF-CAL and the value on the Fault Counter match
press the “R” button to redisplay the set point value “S.01.0”. Repeat these
steps until all calibration values are within tolerance.
Note: Calibration intervals begin at 1kV and are to be performed at 1kV increments.
12. Press the “R” button until the Fault Count display does not have the S or *.
