WARNING
BEFORE USING

• Never cut the internal or external ground wire of a product or disconnect the wire connected
to the protective ground terminal of the instrument because doing so may cause electric
shock or damage to the instrument.
• Before connecting the instrument to the device under measurement or external control
circuit, make sure that protective earth is securely made and that the the power is OFF.
Connecting to external equipment without protective earth or while the power is still ON
may cause electric shock.
• Before touching parts of the instrument where voltage/current is output or circuits connected
to parts where voltage/current is output, make sure that the power is OFF. Touching such
parts without turning the power OFF may cause electric shock. Be sure to sufficiently
insulate circuits from output voltage/current.
• Be sure that the power always meets specified voltage, current, and frequency requirements.
Use of power other than that specified may cause electric shock, fire, or damage to the
instrument.
• If you hear thunder, do not touch any metal parts of the instrument or the plug because there
is a risk of electric shock from conducted lighting. Do not use this instrument outdoors if

• Phase difference detector
Detects the phase difference between two torque signals to oscillates a pulse train corresponding to phase
variation.
• Torque counters
Since the TS-3200A has a short sampling time, it is provided with two torque counters: one counts the
pulse train which is proportional to the phase difference and the other counts the pulse train with a fixed
phase difference (360 degrees) to obtain T1 and T2, respectively.
• Rotational counters
Like the torque counter unit, the TS-3200A is provided with two rotational counters: one counts the
number of input signal pulses, N, and the other counts the total value of the integrated period, T.
Although the sampling time synchronizes with the torque counter units, the count times of the two
counters are not the same because of different input signals.
• Memory unit
This unit consists of nonvolatile memory which memorizes various parameters (including N-0
compensation) specified by key entry.
• Data processing unit
This unit consists mainly of a microprocessor to perform high-speed operation, time constant operation,
sequence control, and interface control.
It processes high-speed operation for each sampling time (4ms/optionally 1ms) based on the expression
below. The unit counts the pulse train which is proportional to the phase difference and the pulse train
with a fixed phase difference (360 degrees) to obtain T1 and T2, respectively.

1.5 Precautions on Wiring of Torque Meter
In recent years, increasing number of test devices using or measuring inverters have been used. An
inverter emits noise because of the operating principle and may affect other devices near it. Torque meters
are not an exception. The degree of effect depends on the amount of noise generation, installation
condition of signal lines, device installation condition, distance between the inverter and device, and other
factors. Trouble caused by noise from the inverter can be reduced by observing the following precautions
on wiring installation. For other causes than noise from the inverter, it is recommended that the following
precautions be observed at the time of installation.
(1) Take measures for radiation noise on the side of the inverter unit and the motor.
(2) Separate the input and output lines of the main circuit of the inverter from the power and signal lines of
the torque meter (cables for torque counters and rotational counters).
The rough standard distance of separation is 300mm or more. If separation is difficult or
ineffective, apply metal conduit tubes to the power and signal lines of the torque meter
and then connect one side of the metal part to a good ground.
(3) Use the supplied cables for the power and signal lines of the torque meter.
(4) Connect the rack for the torque detector to a good ground.
(5) Connect the torque meter to a power circuit which is isolated from the power circuit of the
inverter.
If isolation results in no improvements, install a noise cut transformer for EMI measures,
etc.
