Product Description

Isoprobe Electrostatic Voltmeter, 3kV

244a_newModel 244A-2 Isoprobe Electrostatic Voltmeter

Small, lightweight instrument measures ±3 kV quickly (<2 ms to  1 kV). Has 4-digit LCD display and ±3 volt analog output. Also available Model  244AK-2 has ±15 volt output (1/200 of input). Ideal for electrophotographic,  xerographic, electret applications and for charge accumulation monitoring and  control.

Feature 1: Fast speed of response
Feature 2: ± 3kV range, auto polarity
Feature 3: Accuracy better than 0.1% at almost any probe-surface  spacing
Specification:

Size 10cm (4″) H x 21.6cm (8%”) W x 35cm (14″)D).
Weight 3.2 kg (7 Lb)
Power Requirements 100, 115 or 230 VAC ± 10%, 50-60Hz. 15W max.
Meter Range ± 3 kV, auto-polarity
Setting Time: 3 ½ mS for 1% of step input @ 1 kV, measured at probe.
Surface Resolution: Determined by probe aperture size and surface-probe separation. Standard  Type 1017AE & 1017AS probes with 1.75mm (0.07″) aperture will resolve a 2.5mm  (0.10″) spot @ 0.5mm (0.02″) separation.
Step Response:

Response Speed for typical input step: < 3mS (10%-90%)

1000V step:  < 2 ½ mS 10% to 90%)

2000V step: < 3 ½ mS (10%-90%)

3000V step:  < 4 mS (10%-90%)

Frequency Response: Small signal frequency response typically ± 3dB to >300Hz.
Drift: < 0.01V/hr after 1 hr warmup (0.003V/hr typical). Not measurably affected  by 10 ° C temperature variation or changes between 10% and 90% relative  humidity.
Noise: < 0.3Vrms or 2V peak-to-peak wide band. (referred to input).
Recorder Output BNC, Compressed analog output (1/1000 of input or optional Model 244K, 1/200 of  input) for external loads >=1K ohms.
Display Type: LCD
Accuracy 0.1% ± 0.003%/° C over 20° -40° C range (at recorder output). Usable to  50° C.
