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.
1. Less than 0.01 V/hr. non-cumulative after 1 hr. warm-up in an
uncontaminated atmosphere.
2. 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.).
