Model 610C/610CR Specifications
AS A VOLTMETER
RANGE: O.OOIV full scale to 100V in eleven Ix and 3x ranges.
ACCURACY: ±I % of full scale on all ranges, exclusive of noise
and drift.
ZERO DRIFT: < l mV per 24 hours; <150f.!V per °C after 30-
minute warm-up.
METER NOISE: ±25f.!V maximum with input shorted on most
sensitive range.
INPUT IMPEDANCE:
>
I 014Q shunted by 20pF. Input resis­
tance may also be selected in decade steps from 10 to lO"Q.
AS AN AMMETER
RANGE:
1O-14A full scale to 0.3A in twenty-eight Ix and 3x
ranges.
ACCURACY: ±2% of full scale on 0.3 to I o-IIA ranges using the
smallest available multiplier setting; ±4% of full scale on
3 x 10-12 to lerl4A ranges.
METER NOISE: <±3 x lo-lsA.
OFFSET CURRENT: <5 xlo-'SA.
AS AN AMPLIFIER
INPUT IMPEDANCE:
>
lO'4Q shunted by 20pF. Input resistance
may also be selected in decade steps from 10 to lO"Q.
OUT PUTS: Unity-gain output and either voltage or current
recorder output.
UNITY-GAIN OUTPUT: At DC, output is equal to input within
lOppm, exclusive of noise and drift, for output currents
�IOOf.!A. Up to ImA may be drawn for input voltages �1OV.
Output polarity is the same as input polarity.
VOLTAGE RECORDER OUTPUT: ±3V for full scale input.
Internal resistance is 3kQ. Output polarity is opposite input
polarity.
GAIN: 0.1, 0.3, etc. to 3000.
FREQUENCY RESPONSE (within 3db): DC to 40kHz at a
gain of I and lower, decreasing to DC to 100Hz at maximum
gain. Full output response limited to 3kHz on any gain.
NOISE: <3% rms of full scale at gain of 3000, decreasing to 1%
at gains below 100.
CURRENT RECORDER OUTPUT: ± l mA for full scale input,
variable ±5% with 1400Q recorders.
Specifications subject to change without notice.
AS AN OHMMETER
RANGE: lOOQ full scale to 1014Q in 25 linear Ix and 3x ranges.
ACCURACY: ±3% of full scale on 100 to 1OIOQ ranges using the
largest available multiplier setting; ±5% of full scale on 3 x 1010
to 1014Q ranges.
AS A COULOMB METER
RANGE: lerI3C full scale to IO-sC in seventeen Ix and 3x
ranges.
ACCURACY: ±5% of full scale on all ranges. Drift due to offset
current does not exceed 5 x lo-lsC per second.
GENERAL
POLARITY: Meter switch selects left-zero (positive or negative)
or center-zero scales. Output polarity is not reversed.
CONNECTORS:
Input: Teflon-insulated UHF; ground binding post.
Voltage or current output: Amphenol 80-PC2F.
Unity gain output, chassis ground: Binding posts.
POWER: 105-125V or 210-250V (switch selected), 50-60Hz,
lOW.
LINE STABILITY: A 10% change in line voltage will cause
<I Of.! V meter deflection on all ranges.
DIMENSIONS, WEIGHT:
275mm high x l75mm wide x
290mm deep (10.75 in x 7 in x 11.5 in). Net weight 4.8kg
(11 lb).
ACCESSORIES SUPPLIED: Mating input and output
connectors.
