Atec Megger-247000 Series - Manual (Page 2)

247000 Series
Digital Low Resistance Ohmmeters
Low-Range/High-Current Models
Cat. No. 247100 and 247101
These instruments are used when a continuous test current
of 100 amperes is required. These models include a
separate 100 ampere current supply module with a
modified standard battery-powered 10 ampere system.
These combinations provide a sixth range, 0 to 599.9 µ Ω,
with the 100 ampere current.
For 100 ampere measurements, an interconnecting cable
from the 100 ampere current supply module is plugged
into a special receptacle on the measuring module.
When the 100 ampere range is not used, a jumper plug is
inserted in place of the interconnecting cable.
This feature allows the measuring module to be used
as a standard battery-powered, 10 A instrument.
Cat. No. 247100 meets ANSI C37.09, Test Procedure for
AC High Voltage Circuit Breakers.
FEATURES AND BENEFITS
■ Resolution as fine as 0.1 µ Ω
■ Standard accuracy of ±0.25%
■ Kelvin-type, four-wire measurement eliminates errors
caused by lead and contact resistances.
■ Digital readout with automatic zero circuit eliminates
field test inaccuracies.
■ Broad line of test leads is available to simplify and
enhance data collection.
The Low-Range DLRO, Cat.
No. 247002, features an extra
range and rugged, Single-Pak
design.
Low-Range/High-Current Model Cat. No. 247101 consists of a
Single-Pak DLRO, Cat. No. 247001-3, and separate 100 ampere
test current supply, Cat. No. 247120. The 100 ampere supply
also may be ordered as an option.
