displayed.
% Deviation:
Displays % deviation from entered reference value.
Ax+B:
Linear scaling of results, with offset.
Limits:
Reading displayed with HI, LO, or PASS with respect to user-defined
high and low limits.
Min/Max:
Minimum and maximum reading stored.
Power:
Calculates V2/R and displays in Watts with respect to a user-defined
impedance.
VA:
Calculates and displays Volts x Amps.
Data Logger:
Manual or automatic storage of 100 measurements. Storage interval

INTERFACES
Full remote control facilities are available through the RS232 (all models) or GPIB (alternative
mains-only version) interfaces.
RS232:
Baud rates 2400, 9600 or 19200. Complies fully with the ARC
(Addressable RS232 Chain) interface standard. Address selectable
from the front panel. Operational only when the meter is powered from
the AC input.
GPIB (IEEE-488):
The meter can be specified with an IEEE-488 interface. This is an
alternative version which operates only from AC mains; IEEE-488 is
not a retrofittable option. Address selectable from the front panel.
POWER REQUIREMENTS
AC Input:
220V-240V or 110-120V AC ±10%, 50/60Hz, by internal adjustment;
5VA max. Installation Category II.
Batteries:
6 x C cells, disposable or rechargeable.
Battery Life:
>150 hours from alkaline cells; typically 70 hours from rechargeable
cells.
