Trek Model 800 Infinitron

Ultra-High Impedance Voltmeter

The ±100 V Trek Model 800 Infinitron Voltmeter may be
used in either contacting or non-contacting mode to
acquire precision surface voltage measurements. It is
especially beneficial when used with applications that
demand infinitely high loading impedance levels far
beyond the reach of currently available high impedance
voltmeter instruments. The Model 800 comes with a
guarantee of virtually no modification of the object being
measured. This allows the instrument to indicate, with
high precision, the voltage level of both conductive and
insulative objects and surfaces.

Hold Mode

Controlled by local pushbuttons or
remotely through HOLD BNC Connector

Zero

Controlled by local pushbuttons or
remotely by applying a momentary (100
ms minimum) TTL low through a
designated BNC Connector

Null Offsets (Auto Null
Adjustment)

Nulling of the input voltage and current is
necessary when the unit is first powered on,
or when the display prompts that an auto
null adjustment is necessary. Placing the
probe in a holster on the side of the unit
and pressing the NULL OFFSETS
pushbutton provides nullification of the
voltage offsets and the “leakage” currents,
which are dependent on environmental
conditions. An audio tone will signal when
the null offsets process is completed.

TEMP/RH Meter Connector

A connector receives an input from an
optional thermo hygrometer (Omega Model
HH311) and enables the Model 800 to
display environmental data on the LCD
screen.
