DANGER
Do not exceed the maximum input voltage and current. Doing so can
damage the unit or cause a serious accident.
CAUTION
The measurement input terminal (BNC) and chassis of the 3193 are
not isolated from each other.

9603 EXTERNAL SIGNAL INPUT
UNIT (Option)
17.1 Overview
The 9603 EXTERNAL SIGNAL INPUT UNIT, when installed
in the 3193, allows an analog signal output by another device
to be input and combined with other measurements. In
particular, combination with a motor torque gauge or rotation
counter allows the 3193 to compute and display the motor
power and efficiency.
･
The 9603 is a factory-fitted option. It therefore requires the 3193 unit for
calibration or repair.
･
For accurate measurement, allow one hour for warming up before use.
･
It is not possible to measure torque or rotation speed with the 9603 alone. It
must be combined with a torque gauge or rotation counter with an analog
output.
･
It may not be possible to obtain accurate measurements close to a
transformer or conductor carrying a large high-frequency current, or close to
any device such as a radio transmitter generating a strong magnetic field.
･
When no signal is input, cover the BNC connector with the supplied cap.
