Features
LCD Display Screen with
LED back-light 127 mm x 38 mm (5" x 1.5") screen
displays prompts and voltage
measurements with date and time
Display Resolution 240 x 64 pixels
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.
