ORDERING INFORMATION
OPTIONAL ACCESSORIES
Input Voltage Protection
To protect the instrument when testing battery straps, this
option provides input protection against accidental
overvoltage up to 30 volts.
The option should not be specified when the instrument
will be used to test transformers and other inductive
components. This option is available on Cat. No. 247000,
247001 and 247002 only. To order, add –11 to instrument
Cat. No.
100-Ampere Adapter Plug
Cat. No. 247000 and 247001 can be ordered with an
adapter plug to allow use with the 100 ampere current
supply, Cat. No. 247120.
This capability is required by some standard methods of
testing large switchgear. ANSI C37.09, Test Procedure for
AC High Voltage Circuit Breakers, and IEC
Recommendation, Publication 56-4, High Voltage
Alternating Current Circuit Breakers Cat. No. 247101, are
two such standards. Cat. No. 247100 comes standard with
this option. This option is not available with Cat. No.
247002. To order, add –3 to instrument Cat. No.
Calibration Shunts
These four-terminal calibrating resistance standards feature
a conservative current rating to ensure against overheating.
Each shunt provides two current terminals with knurled
Allen-head cap screws and two potential terminals with
slotted screw heads. Accuracy is ±0.25%.
