6-2. POTENTIOMETRIC RECORDER
The Fluke Model A-70 Self Balancing Potentiometric Recorder
is a special purpose high sensitivity recorder developed for
monitoring voltages measured by the
800 Series
Differential Voltmeters. In addition to providing a permanent
record of results, the recorder allows unattended monitoring of
various voltages from 0 to 500 volts for long periods of time. A
sample voltage which varies in direct proportion to the source
under measurement is obtained from the voltmeter null
detector by connecting the recorder to the output terminals at
the rear of the voltmeter. A gain adjustment control adjacent to
the voltmeter output terminals allows the sample voltage to be
adjusted such that full-scale meter deflection equals full-scale
recorder deflection. The large leakage resistance (500,000
megohms) between the recorder input posts and chassis is
such that the inherently high accuracy of the Fluke Differential
Voltmeter is generally not impaired in any way.
