G. FREQUENCY RESPONSE:

Small signal bandwidth is related to amplitude. At 11 5 volts RMS bandwidth is

typically -3db at 300 Hz.

H. DRIFT:

Drift is specified with 1017S or E probes at .005" (.13mm) probe-to-surface

spacing, purged in a clean stable atmosphere.

Less than 0.01 V/hr. non-cumulative after 1 hr. warm-up in an

uncontaminated atmosphere.

Indiscernible effects of line voltage variations, 10 to 90% relative humidity,

15°C to 35°C temperature range.

I. NOISE (Referred to Input):

Probe-to-surface spacing = .005" (.13mm), 1017S or E probe 600 mV RMS or 2V

p-p wideband typical. See graphs for other aperture or probe-to-surface

spacings. Also check individual probe specifications.

J. SURFACE RESOLUTION:

Surface resolution is dependent upon probe aperture size and probe-to-surface

spacing. Refer to probe literature for specific information relative to probe being

used.

K. PROBE-TO-SURFACE SPACING ERRORS:

Independent balance and zero adjustments allow voltage readings independent

of probe-to-surface spacing. The stability of these adjustments relates to the

same factors as does drift.

L. METER:

Four digit auto-zero, auto-symmetry, auto-polarity meter, with a liquid crystal

readout.

M. RECORDER OUTPUT:

A low voltage HV/1000 output is provided with a 3V max. output. The output is

capable of driving 10000 or greater.

N. POWER INPUT:

100, 117 or 230 volts ±10%, 50/60 Hz., 15 watts max.

O. PROBE DIMENSIONS:

Model 1017 series probes are 0.35" (8.9mm) x .35" (8.9mm) x 2.85" (72.4mm);

weight 6% oz. (180 gm).

P. SIZE AND WEIGHT):

Size 4" (10.2cm) high x

8^/2"

(21.6cm) wide x 15" (38.1 cm) deep. Weight 7 lbs. 3

oz. (3.26kg.).
