PERFORMANCE

All specifications are with a 6000B-8 probe at a probe-to-surface separation of 2 mm.

Measurement Range
0 to ±3 kV DC or peak AC.

Accuracy
Voltage Monitor Output
Better than ±0.05% of full scale.
Voltage Display
Better than ±0.1% of full scale referred to the voltage monitor.

Speed of Response (10% to 90%)
Less than 3 ms for a 1 kV step change.

Stability
Drift with Time
Less than 100 ppm/hour, noncumulative.
Drift with Temperature
Less than 100 ppm/°C.

PRODUCT FEATURES

Zero Control
A multiturn control to produce zero volts output when the probe is coupled to a known zero volt surface.

Response Control
A ten position push-button switch that adjusts the gain of the Model 347 to optimize the AC response. The response control is normally adjusted when changing the type of probe being used or when changing the probe-to-surface separation.

Voltage Monitor Output
A buffered output providing a replica of the measured voltage.
Scale(s)
Model 347-3
1/100th of the measured voltage.
Model 347-15
1/1000th of the measured voltage.
Output Noise
Less than 2 mV rms (measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter).
Output Impedance
Less than 0.1 Ω.

Voltage Display
3 3/4-digit LED display.
Range
0 to ±3000 V.
Resolution
1 V.
Zero Offset
Less than or equal to ±1 count.

Digital Enable
A TTL compatible input to turn on and off the internal high-voltage power supply. A TTL high (or open) will turn off the high-voltage. A TTL low will turn on the high-voltage.
