Introduction
This instrument is a mains operated, high performance autoranging multimeter providing 5½ digit
resolution (± 210000 counts) switchable to 4½ digits (± 21000 counts) for a higher reading rate. It
has a 7-segment l.e.d. display coupled with l.e.d. annunciators for displayed units and instrument
status.
The main features are :-
•
ARC serial interface as standard, GPIB optional
•

Four-terminal Ohms
•
Selectable audible continuity checker
•
T/Hold mode - holds onto a stable reading until updated
•
Display nulling - a different value can be set up for each function
•
100 point data logger - circular or linear store
•
Measurement post-processing:-
percentage deviation from a user-entered reference
decibel calculations
linear scaling with offset
limits comparison for go/no go testing
automatic storage of minimum and maximum readings
•
Selectable digital filter
•
Programmable buzzer
•
Battery-backed RAM :-
