Calibration

The Spark Tester may be reasonably expected to retain its accuracy for a period
of one year from the date of calibration under conditions of normal use.

CAUTION:

The calibration procedures listed below are to be performed by

qualified service personnel experienced in high voltage safety procedures only.
Failure to follow these procedures may result in danger to personnel and
equipment.

The following is a list of recommended equipment for use in calibrating the DC-B.

•

Electrostatic Voltmeter (EVM)

–

Manufactured by Sensitive Research

•

ST-CAL with LFVM

–

Manufactured by Clinton Instrument Company

ST-CAL Calibration

The DC-B can be calibrated through an automated process using the STCAL
system with an LFVM.

To perform the calibration with the STCAL please follow the instructions for the
STCAL system.

EVM Calibration Procedure

The EVM has a mirrored area to assist in eliminating errors in reading. The correct
way to read the meter is to move the viewing position (your eye) until the
reflection of the needle in the mirror is directly behind the needle itself, and
observe the needle position on the scale. This eliminates any parallax error that
might result from viewing the meter at a slight angle.

Connecting the EVM

1.

Before connecting to the EVM, turn ON the spark tester and adjust the
voltage to 0 using the VOLTAGE ADJUST down arrow button. Turn OFF
the spark tester.

2.

With the power to the DC-B Spark Tester turned off connect the high
voltage input on the EVM to the Spark Tester electrode. Use the shortest
high voltage lead possible.

For bead chain and brush electrodes con-

nect the alligator clip directly to the electrode. For roller type
electrodes you may need to wrap the high voltage roller with unin-
sulated wire and connect the alligator clip to the wire.

3.

Set the EVM range Selector to the 5kV range. Then Zero the EVM.
