1.1 Overview
TC-32K is a compact hand held instrument that you can hold with one hand. Its splash proof construction
allows safety use outside. The terminals connecting the sensors are one-touch type, and provide easy
connection with the lead wires and banana plugs, and speedy measurement. You can set the sensor mode,
coefficient, and initial values of up to 20 channels and record their data, so it is easy to organize the data
even when you are moving around multiple fields to collect data. Also, by using a dedicated switching
box CSW-5B/CSW-5B-05, auto measurement of 5 points becomes available. In addition, TC-32K has
various functions including the interval timer, data memory, data storage by Compact Flash
card, and connection with PC for control and data transfer. With the resistance check and insulation
resistance check functions, you can check strain gauges and strain gauge type transducers.

Connect the earth wire to the input terminal E. Use a thick
earth wire as much as possible and ground with the
shortest length. Grounding is also effective for
prevention of noise from lightning or heavy equipments.
If peal of thunder is near, or there is a
risk of lightning stroke, stop the
wiring works for grounding and
power source, operation of the
instruments, and keep away from the
instruments. If being hit by a stroke
of lightning during these works, you
may get an electric shock, get
burned, or even die.
Danger
2.3 Instructions for field measurement
When installing the TC-32K together with the switching box CSW-5A or CSW-5B for long-term
measurement, be sure to arrange grounding correctly. Also, if there is a risk of lightning stroke, be sure to
ground correctly.
■ Grounding
■ Lightning protection
In fields where cables between switching boxes and sensors are extended, pulse generated by induction of
lightning stroke may cause serious damage on sensors, switching boxes and instrument, and even break
them even if they are not hit by lightning stroke directly. Therefore, proper countermeasures against
lightning are essential.
Cable layout
For sensor cables, use dedicated cables for transducers such as rubber sheathed shielded cable. In
order to minimize the difference of induction voltage against the ground, avoid wiring in midair, and
lay wires down on the ground. If it is impossible to lay them down on the ground (for example if
cables are installed around steel towers), use the arrester for sensors mentioned in the next article.
Arrester for sensor
NZ-6B is the 6-wire system arrester for strain gauge type transducers and also applied to strain gauges.
Insert the arrester near the sensor as much as possible. Although the input terminals of TC-32K have
simple built-in arresters for sensor, it is recommended to install another arrester for sensor together to
make assurance double sure.

4.1 Monitor screen outline
After power-on, the monitor screen appears on the display. This screen displays measurement
values (monitored values), time, status, and other information. You can change the screen to set
other various functions using key switches.
4.2 Monitor display
With the monitor display function, measurement values that the instrument is monitoring are
displayed on the screen all the time. Displayed data varies according to the monitor display
system that has been selected in advance.
Three display methods are selectable, which are value monitor, waveform monitor and monitor
off. For the value monitor, it is selected between 1-channel and 5-channel with dedicated
switching box connected (when multi-channel mode is selected).
The following sections show the examples of the monitor screen and explain items on each
screen.
■ Value monitor
The screen displays measurement values of the selected channel. The number of channels that can
be displayed on the screen is up to five (when multi-channel mode is selected).

■ Meaning of displayed value
When the sensor is connected to the input terminal and the sensor and the measurement system
have no problem, a certain value is always displayed. However, if the sensor is not connected,
or connected but its wire is broken, or the input value is over the measurement range defined in
the specifications, the following indications are displayed to alert, instead of measurement values.
The indication that appears when a problem occurs, and supposed cause are shown below:
[ * * * * * * * ] Open data
The sensor is not connected, or the sensor cable is broken.
[ + * * * * * * * ] +Over data
The input value is over the measurement range in the + direction.
[ - * * * * * * * ] -Over data
The input value is over the measurement range in the - direction.
[ * * * * I * * * ] Initial value over data
The initial value (initial unbalanced value) is over the initial value storing range.
[ ! ! ! ! ! ! ! ] Indication digits over
The indication digits (before the decimal point) are insufficient for displaying the
measurement value.
