8.0 GENERAL SPECIFICATION

This specification applies to the instrument as a whole.
8.1 ELECTRICAL
Input Protection: The inputs will withstand 300 V d.c. or 300 V a.c. up to
60 Hz. with minimum source impedance of 1.5 Ω.
Voltage Test Accuracy: ±2% ±1 digit
Voltage Test Range: 0 – 250 V DC measured between terminals E to A or
E to B, E being positive, minimum source impedance
1.5 Ω
Batteries: Six LR6 (AA) type batteries, Manganese-alkali or
nickel-cadmium or nickel-metal-hydride cells
Nominal voltage: 9 V for Alkali of 7.2 V for NiCad.
Low battery warning occurs at 6.5 V
Battery Consumption: 140 mA nominal, 180 mA with backlight
18
Safety: The instrument meets the safety requirement of BS EN 61010-1:
1993 including Amendment 2: 1995-06. As its primary use is for
Telecomm testing the instrument also adheres to IEC 60950,
third edition: 1999-04 and is rated for use on TNV-3 circuits. If it
is to be used in situations where hazardous live voltages may be
encountered then an additional blocking filter must be used. Note
that this will prevent the operation of the instrument in Bridge and
Meter modes.
EMC: Complies with Electromagnetic Compatibility
