Calibration and Software Version Information
This will allow the user to see the version of the software as well as who performed the last
calibration.
1.
Turn off the HT-2800P tester.
2.
Hold in the
Reset
button while turning on the tester.
3.
The meter will display 3 items:
A) The model number of the tester, 2800.
B) The version of the software
C) Laboratory number to designate who performed the last calibration:
(1= Compliance West USA, 2= another company)
Continuity Calibration Adjustment
Use the following procedure to adjust the Pass/Fail point of the Ground Check test. Pot P101 is
located on the top board near the left edge.
Two leads, each having a banana plug on one end and an alligator clip on the other, and a 3 ohm
1% resistor, are needed for this calibration procedure.
NOTE
: It is possible to adjust the Pass/Fail point through a range of approx. .5 -5 ohm using the
range of P101. If a special calibration was performed by the factory, it will be noted on a
calibration sticker on the inside of the enclosure. If no special calibration sticker exists, the
factory calibration point was 2.85-3 ohms.
If a special calibration point is desired, change the value of the 3 ohm resistor used in the
following procedure to the desired value of the Pass/Fail point.
1.
Perform the voltage calibration adjustment procedure above.
2.
Remove all test leads from the HT-2800P.
3.
Connect the banana plug end of one lead to the
RETURN
jack and the alligator clip end to
the 3 ohm resistor.
4.
Connect the banana plug end of the other lead to the round (grounding) jack of the
DEVICE
receptacle and the alligator clip end to the 3 ohm resistor.
5.
Turn the
Ground Check
switch on the rear panel to the On position.
6.
Push the
RESET
button, then the
TEST
button.
7.
The
Ground OK
or
Ground Open
LED will immediately light. Push the
RESET
switch.
a. If the
Ground OK
LED lights, turn P101 clockwise and push the
TEST
button.
b. If the
Ground Open
LED lights, turn P101 counterclockwise and push the
TEST
button.
8.
Continue adjusting P101 until the highest clockwise setting which lights the
Ground OK
LED has been attained.
Voltage Calibration Adjustment
Use the following procedure to calibrate the output voltage.
1.
Ensure that all test leads are removed from the HT-2800P.
2.
Turn OFF the HT-2800P tester.
3.
To enter the
Calibration Mode
you MUST follow the following sequence:
- Hold in both the
Test
and
Reset
buttons.
- Turn on the HT-2800P tester.
