G. Power Entry Module:
The Power Entry Module combines power inlet, switch and fusing system. Power supply voltage is usually factory
preset for local conditions. When in doubt, check! See Appendix II for details.
H. Ground jack:
Instrument ground - the reference point for measurement. The instrument is normally grounded through the power
cord. This jack accepts a standard size banana plug (0.175” [4.4mm] across flats).
I. Recorder output:
The signal at this BNC jack is a low voltage representation of the input. The output voltage is equal to the measured
voltage measured divided by 1000 or 0 to ±3 volts for full scale (±17 volts full scale typical for ÷200 option and ±19
volts full scale typical for ÷100 option). Representative uses include observation or recording of waveforms or levels
seen by the input, monitoring of safe/unsafe electrostatic operating conditions in equipment and low level process
control in electrostatic feedback loops.
J. Probe receptacle:
Duplicate of (F) provides the option of a probe connection at the rear of the instrument. Only one or the other may
be used. Model 279 will not support two probes simultaneously.
