Trek Model PD06078 Electrostatic Voltmeter (ESVM) is a four (4) channel voltage measuring instrument which is ideally suited to monitor critical operations associated with semiconductor, LCD, electronic assembly, and other processes where static charge accumulation poses a threat to production yields or product quality.

The Model PD06078 contains four (4) Electrostatic Voltmeters in a single enclosure. Each channel features a measurement range of 0 to ±10 kV and accuracy better than 5% reading plus ±0.2% of full scale over the probe to surface separation distance of 15 to 30 mm.

Dimensions
177 mm H x 203 mm W x 228 mm D
(7” H x 8" W x 9" D).

Weight
8 lbs. (3.6 kg)

Power Supply Options
A two (2) pin [Mate-n-Lock] connector
or a DC power input for 24 V DC ±10%, 1.5 A supply, 3 A initial peak current.
(An Universal Power Adapeter is optional.)

Output Connector
(one for each channel)
A six position output connector
(6P/4C) provides connections for
the output voltage monitor, the
current output, and a ground
connection.

Operating Conditions Temperature
15 °C to 35 °C.
Relative Humidity
5% to 85%, noncondensing.

Power ON/OFF
Front panel switch.

Probe Connector Locations
Rear panel.

Four (4) Position Channel Switch
Selects one of the four channels outputs for display on the DPM.

Digital Panel Meter (DPM)
3½ digit LED voltage display.
Range
0 to ±10.00 kV.
Resolution
10 V.
Zero Offset
Less than or equal to ±2 counts.

ZERO Control
(one for each channel)
Rear panel potentiometer used to
produce zero volts output when
probe is coupled to a known zero
voltage source.

Monitor Output
(one for each channel)
Scale Factor
The voltage monitor is scaled at
1/1000th of the measured
voltage for each channel.
Output Noise
Less than 10 mV rms (using the side view probe and measured using the true rms feature of the Hewlett Packard Model 34401A digital voltmeter).
Output Impedance
47 Ω.

Current Output
(one for each channel)
Provides a current of 4-20 mA that
represents measured voltages
-10 kV to +10 kV.

Ground Connections
Four (4) banana jacks and a
designated terminal on the output
connector are all tied to chassis
ground.

The probes are chopper stabilized for drift-free operation.
