In its base
configuration, Model 2004 is a 4 3/4 digit DC voltmeter which
provides exceptionally high resolution, accuracy, and temperature
stability. The standard display range is ±39,999 counts.
Extended-range options are available to ±49,999, ±59,999
or ±69,999 counts. Accuracy is 99.99% of reading. Span tempco
is ±10 to ±20 ppm of reading/°C, made possible
by precision wirewound resistors. The 2004 also features exceptional
noise rejection. Its conversion circuit uses a crystal oscillator,
which is tuned for either 50 or 60 Hz rejection.
BCD OUTPUT STANDARD
Unbuffered, non-isolated parallel BCD output is a standard
feature of the 2004 and is implemented on the main circuit board.
It is good for about 1 ft and can be used to interface the 2004
to a Model 872A comparator or a Model 820A printer. Additional
data and control outputs can be provided by an optional upper-board.
OPTIONS
The meter main assembly can be electrically configured for
four input ranges, four display spans, three round-off modes for
display stability, and high-impedance 3-wire ratio input. Upper-board
options include four BCD output boards and a single-setpoint controller.
Mechanical options for the standard 1/8 DIN case include a screw-terminal
barrier strip for signal and power and a splash-proof lens cover
which meets NEMA-4 requirements. A NEMA-size case is optional.
