Safety Notes

This product is designed to conform to IEC 61010 Safety Standards, and

DANGE R

has been thoroughly tested for safety prior to shipment. However,
mishandling during use could result in injury or death, as well as
damage to the product. Be certain that you understand the instructions
and precautions in the manual before use. We disclaim any
responsibility for accidents or injuries not resulting directly from
product defects.

This Instruction Manual provides information and warnings essential for
operating this equipment in a safe manner and for maintaining it in safe
operating condition. Before using this equipment, be sure to carefully read
the following safety notes.
Read the Instruction Manual supplied with the 3194 product very carefully,
and follow the indications given under "DANGER," "WARNING,"

Notes on Use

In order to ensure safe operation and to obtain maximum performance from
the product, observe the cautions listed below.

The measurement input terminal and chassis of the 3194 are not

DANGE R

isolated from each other. Do not exceed the maximum rated working
voltage. Doing so can damage the product or cause a serious accident.

NOTE

The 9603-01 is a factory-fitted option. It therefore requires the 3194 product for

calibration or repair.
For accurate measurement, allow one hour for warming up before use.
The 9603-01 can be used together with a strain gauge type torque meter, but

depending on torque meter specifications, the combination may not work.

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.
To prevent damage to the product, cover the input connector with the supplied

ca

when no signal is input.

Overview

The 9603-01 EXTERNAL SIGNAL INPUT UNIT can read
signals from a strain gauge type torque sensor directly to the

Channel A

3194 product. Further, tachometer signals (analog or pulse)
input via the 9603-01 can be used by the 3194 to calculate and
display motor power and efficiency.

Setting Method

3.1 Changing the chA Input Connector

chA input is used to select either the strain gauge input (7 pin connector) or
DC voltage input (BNC pins).
Press the

STATUS

key to switch to the external input screen.

NOTE

Input is switched using the internal circuits but do not connect to connectors that
are not being used.

3.2 Changing the Range

3.2.1 Strain Gauge Input

Channel A (Strain Gauge) can be used for the torque meter output, and has
three ranges: 1 mV/V, 1.5 mV/V, and 2 mV/V. The full scale screen display
values for these ranges are 1.0000, 1.5000, and 2.0000 respectively (when
the scaling value is 1). The scaling value is calculated as follows:
Scaling value = (rated torque value for the combined torque meter) / (full
scale value for the range) After selecting the range, set the units to finish
setting channel A.

When a rated torque of 100 N.m and a rated
output of 1.5 mV/V torque sensor are combined:

meter's power cord and disconnect the other wiring before connecting
the GP-IB or RS-232 cable to the interface connector.

CAUTION

NOTE

Turn the power off when connecting the personal computer to the power
meter. Connecting or disconnecting cables while the power is on could
damage the equipment.
After connecting the GP-IB or RS-232C cable, always be sure to secure
the connection with the screws on the connector.

The 3194 MOTOR/HARMONIC HiTESTER is fitted as standard with a GP­IB/RS-232C interface. Using this interface, all of the functions of the
product can be controlled from a personal computer by remote control, for
the acquisition of harmonic measurement data.
This section lists the extra commands added for measurement.

This section explains only commands added for the 9603-01.
For details on operation of the GP-IB or RS-232C interface, first refer to
Chapter 12, "GP-IB/RS-232C Interface" in the instruction manual of the

3194.

It is not possible to use simultaneously both GP-IB and RS-232C interfaces.

There are two input connectors on chA. Each one corresponds to "strain
gauge input" and to "DC voltage input." On the 3194, it is necessary to set
which input connector to use. There is one input connector on chB. It
corresponds to "DC input" and "pulse input."
On the 3194, it is necessary to set the type of input.

Internal Block

Diagram

The voltage input through the connector is converted, in differential and
range circuits, to a voltage proportional to the input voltage, and transferred
to the 3194 proper by an A/D converter.
When measuring a rotation rate by counting pulses, channel B can be
switched so that pulses are counted by the frequency measurement function
in the 3194 proper.
