Warranty:

Monroe Electronics, Inc., warrants that each

instrument and sub-assembly manufactured by them
shall be free from defects in material and workmanship
for a period of one year after shipment from the factory.
This warranty is applicable to the original purchaser
only.

Calibration:

Monroe Electronics instruments are factory-

calibrated prior to shipment. Recalibration should be
performed annually, or more frequently if specified by
contract or company policy. Your instrument should
also be recalibrated any time it has been repaired or
tampered with. We are happy to recalibrate your
instrument for you at a reasonable cost, or provide
information and procedures on calibration upon request.

The finest Electrostatic instrumentation and
support:

For more than 40 years - ever since we invented the
feedback--nulled electrostatic voltmeter, Monroe has
been the technology and quality leader in electrostatic
detection and measurement instrumentation. Today we
offer the world’s most complete array of fieldmeters,
voltmeters, and resistivity meters. Our customers
include the leading makers of photocopiers and laser
printers, converters and microelectronics worldwide.

We know you need quality support as well as

quality products. We pride ourselves on providing our
customers with the most knowledgeable applications
and installation support — as well as superior customer
service.

Specifications:

Range:

±3000 volts, auto polarity.

Accuracy:*

0.1%, ±0.003%/°C over +20 to +40°C
range (at recorder output). Useable to
+50°C.

Speed of
response:*

For typical input step:

<3ms

(10% to 90%)

for 1kV step:

<2½ms (10% to 90%)

for 2kV step:

<3½ms (10% to 90%)

for 3kV step:

<4ms

(10% to 90%)

Settling time: <3½ms to 1% of 1kV step input.

Frequency

Small signal frequency response

response:

typically ±3db to >300Hz.

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.

Noise:*

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

Surface

Determined by probe aperture size and

resolution:

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

Compressed analog output is input

output:

divided by 1000 (optional Model 244AK
has divide by 200) for external loads
greater than 1K

Ω

. Output connector is

BNC.

Output filter:

Bessel low pass filter with 0.7ms
constant delay.

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).

Weight:

7 lb. (3.2 kg)

Power

100, 115, 230 VAC, ±10%, 50/60Hz, 15

requirement:

watts.

Accessories

Manual on CD, line cord, phono plug

Included

Certifications: CE Mark compliant

* Dependent on specific probe model, probe-surface
separation and environment. Specifications shown are
for standard Type 1017AE or AS probes in a normal
laboratory atmosphere. Separation for accuracy and
response speed tests is

” (3mm) and for noise and

drift tests, 0.13mm (0.005”). Performance generally
improves in controlled environments and may be
degraded under exceptional dirty or dusty conditions or
in ambiance of unstable gaseous constituents.
