Information
                                    The Model 335D Voltage Standard combines a dc voltage source
and a dc voltage measurement capability in one instrument.
Precision dc voltages up to 1100 volts, variable by way of
the front panel readout dials, are provided at the OUTPUT
terminals of the instrument. Measurement capabilities from
10 microvolts to 1000 volts are provided by a precision dc
differential voltmeter. This combination allows flexible use
of the instrument as a voltage standaj-4, a differential
voltmeter, or as a null detector.
1-3. Protection against possible equipment failures or
operator errors, which might otherwise damage expensive
instruments, is incorporated. The VOLTAGE TRIP and VERNIER
controls provide a msans of limiting the output voltage
within the range. Should the output voltage exceed a preset
limit, the OUTPUT terminals are deenergized. A current
limiting circuit limits the available current to a level
determined by the setting of the CURRENT LIMIT control.
Therefore, it is able to provide currents up to, but not
exceeding the level determined by the setting of the CURRENT
LIMIT control.
14. The inner chassis and circuitry are surrounded by an
isolation guard which is also isolated from the front panel
and the outside cover. When properly connected, the guard
bypasses any circulating ground currents which otherwise may
cause error. Remote sensing of the output voltage is also
used with the instrument to reduce errors caused by voltage
drop in external cables.
1-5. Most of the instrument circuitry is mounted on modular
plug-in cards. An extender card is provided as an accessory
to aid in the maintenance and adjustment of the instrument.
