Model PCS-2/B |
 |
GENERAL
DESCRIPTION
The Model PCS-2/B is a current-to-voltage calibrator or transconductance
amplifier. The current output is directly proportional to the input
voltages from a high accuracy AC or DC voltage standard. The input voltage
to the unit can be AC or DC up to 1kHz. The ratios of 10 volts to output
is: 1:1, 1:0.1, 1:0.01, 1:0.001 and 1:0.0001. The PCS-2/B is laboratory
calibrated with instruments and load resistors traceable to N.I.S.T.
(National Institute of Standards & Technology). The unit is also equipped
for rack mounting in a standard 19" rack.
Recommended
for DC – Models 511 and 521
The PCS-2B may also be used with AC and DC voltage sources (calibrators)
of other manufacturers.
APPLICATIONS
Applications for
the Model PCS-2B include: Direct Calibration of Watt Meters, Meter Shunts,
AC and DC Current Meters, I to E Transducers, DVMs, DMMs, Relay Coil
Current Testing.

Accuracy: DC, ±(0.01% of
setting + 0.01% of range + 10µA);
AC, ±(0.05% of setting + 0.01% of range + 20µA).
Line Regulation: ±0.0005% for ±10% line change.
Stability: DC, 0.001% of range; AC, 0.005% of range.
Isolation: Floating output; limited only by the isolation of the
driving voltage source. Ripple and Noise, rms, non-additive, in a
band-pass 0.1Hz to 100kHz: 1mA range, 1.5µA; 10mA range, 3.0µA; 100mA
range, 40µA; 1A range, 80µA; 10A range, 375µA.
PROGRAMMING
(IEEE-488.1)
The 5 ranges are GPIB
programmable as well as controlled locally with front panel controls. A
dip-switch, located on the rear panel, is used to set the instruments bus
address.
