Thiết bị đo tĩnh điện Monroe Electronics 244AK

Range:

±3000 volts, auto polarity.

Size:

4 x 8½ x 14 inches (10 x 21.8 x 35.6 cm), 1.75” rack mounting available (1 or 2 per rack).

Settling time:

<3½ms to 1% of 1kV step input.

Speed of

response:

for 2kV step: <3½ms (10% to 90%)

for 3kV step: <4ms (10% to 90%)

For typical input step: <3ms (10% to 90%)

for 1kV step: <2½ms (10% to 90%)

response:

typically ±3db to >300Hz.

Noise:*

<0.3V rms or 2 volts peak-to-peak wide band (bandwidth restricted to<1kHz) referred to input.

Frequency

Small signal frequency response

Drift:*

<0.01V/hr after 1 hr warm-up (0.003V/ hr typical). Not measurably affected by 10°C temperature variation or changes between 10% and 90% relative humidity.

Accuracy:

0.1%, ±0.003%/°C over +20 to +40°C

range (at recorder output). Useable to +50°C.

Weight:

7 lb. (3.2 kg)

Surface resolution:

Determined by probe aperture size

resolution: and surface-probe separation.

Standard type 1017AE & AS probes

with 0.07” (1.75mm) aperture will

resolve a 0.10” (2.5mm) spot at 0.02”

(0.5mm) separation.

Recorder

output:

Compressed analog output is input divided by 1000 (optional Model

244AK has divide by 200) for external

loads greater than 1KΩ. Output connector is BNC.

Accessories Included

Manual on CD, line cord, phono plug

Power requirement:

100, 115, 230 VAC, ±10%, 50/60Hz, 15 watts.
