2. Installation Procedure
Install the MT100 in an indoor location where:
࡮an instrumentation panel can be attached
For information on the panel cut dimensions, see the User's Manual in the supplied CD-ROM.
࡮there is good ventilation
࡮there is little mechanical vibration
࡮the floor is level
Do not install the MT100 in a location where:
㨯the unit is exposed to direct sunlight or near a heater.
㨯there are excessive greasy fumes, steam, humidity, dust, corrosive gas, etc.
㨯the unit is near an electromagnetic field source.
As the panel, use a steel sheet 2mm to 26mm in thickness. Use the panel mount brackets provided with the MT100 to attach it.
There are two panel mount brackets. Be sure to attach them in two opposite locations (up and down or left and right).
Installation Procedure
ԘޓPeel off the masking tape from the surface on which you want to attach a panel mount bracket.
ԙޓInsert the MT100 from the front side of the panel.
ԚޓAttach the MT100 to the panel using the provided mount bracket as shown in the figure below.
i. Use two mount brackets on the up and down or left and right of the case.
(Peel off the masking tape on the case that covers the holes for mount brackets beforehand.)
ii. Attach the two brackets first, then temporarily tighten mounting screws on them.
ԛޓTighten the screws to an appropriate torque.
Next, tighten the mounting screws to an appropriate torque to fix the main unit. While keeping the
main unit roughly at right angles to the panel, bring the mounting bracket into close contact with the
main unit case and tighten the mounting screws.
* The appropriate tightening torque of panel mounting screws is 10 to 12kgf/cm.
Peel off the masking tape.

3. Connecting to an AC Power Supply
No power cord is supplied with the MT100.
Be sure to use a power cord supplied with the optional desktop case (B-541).
Connecting Cables
ԘޓTurn off the power supplied to the MT100 and open the power terminal cover (transparent).
ԙޓConnect the power cord and the protective ground cord to the power terminals.
Use non-insulated solderless ring terminals (for 4mm screws) and insulation caps.
The appropriate tightening torque of screws is 12 to 14kgf/cm.
ԚޓClose the power terminal cover (transparent) and fix it with screws.
ԛޓOpen the front panel and turn on the power switch to power on the MT100.

To avoid electric shocks, check that the AC source for the power supply has been turned off.
To prevent fire, use wires or cables with a performance equivalent to or better than 600V insulated wires
(AWG 20 to 16).
Before turning on the power, be sure to connect the protective ground terminal to the ground at a
grounding resistance of 50ǡor less.
For cables to be connected to a power supply and a protective ground terminal, use non-insulated
solderless ring terminals (for 4mm screws) inserted in insulation caps.
In the power line, provide a switch that can cut off the MT100 from the main power source (double-pole type).
As specifications of the switch, the rated steady-state current must be 1A or larger and the rated
inrush current must be 60A or larger.
Do not insert a switch or fuse in a grounding line.
Use a power supply that meets the following conditions.

4. Connecting Signal Input Cables
This section describes how to connect the signal input cables.
To avoid electric shocks, check that the AC source for the power supply has been turned off before connecting
࡮A large pulling force applied to an input/output signal cable connected to the MT100 may damage a
terminal or the signal cable. Therefore, fix the wiring cords to the back of the installed panel.
࡮To prevent fire, use signal cables with a rated temperature of 70°Cor higher.
࡮Do not apply a voltage higher than the following values to input terminals. If you do, the MT100 may
suffer damages.
Maximum input voltage: ±60VDC
Maximum common-mode voltage: AC33Vrms or ±60VDC
Caution on Connecting Cables
Connecting Cables
ԘޓRemove the terminal cover.
ԙޓConnect signal cables to the input terminals.
The appropriate tightening torque of screws is 12 to 14kgf/cm.
Connect wires to terminals as shown in the following figure after checking them.
ԚޓReinstall the terminal cover.

࡮Connect input signal cables to terminals using insulated solderless terminals (for 4mm screws).
࡮Keep the measuring circuit away from a power cable (power circuit) or a ground circuit.
࡮If the measuring target is a noise source, refer to page 29 and take a necessary measure.
࡮Be sure to connect a protective ground terminal to the ground at a low grounding resistance (50ǡor less).
࡮Be sure to attach a terminal cover when you measure temperatures using a thermocouple.
࡮Do not use a thick wire with a high heat radiation effect when you measure a temperature using a
ޓthermocouple (a wire having a diameter of 0.65mm or less is recommended).
࡮Avoid causing changes in the outside air temperature. In particular, turning on and off the fan near the
ޓMT100 causes significant temperature changes.
࡮If an input cable is connected in parallel with another device, the measurement values of both the
ޓMT100 and the device may be influenced.
࡮Do not turn on and off one of the devices during operation. The other device may be adversely
ޓinfluenced.

5. Connecting Cables to Digital Input and Alarm Output Terminals
This section describes how to connect the signal input/output cables.
To avoid electric shocks, check that the AC source for the power supply has been turned off before connecting cables.
࡮A large pulling force applied to an input/output signal cable connected to the MT100 may damage a
terminal or the signal cable. Therefore, fix the wiring cords to the back of the installed panel.
࡮To prevent fire, use signal cables with a rated temperature of 70°C or higher.
࡮Do not apply a voltage higher than the following values to input terminals. If you do, the MT100 may
suffer damages.
Digital signal terminal: +24VDC at the maximum
Alarm output relay terminal: 250VAC/2A, 30VDC/2A

6. Precautions to Observe When Performing Measurement
Please be sure to read the following carefully in order to prevent electric shocks or shorts.
• Do not apply voltage of AC30Vrms or 60VDC or above between the analog input section and main unit
(GND terminal), or between each analog input channel.
• Do not apply radio-frequency signals with high voltage (50KHz or above).
Input Circuit Diagram for Analog Input (Voltage, Thermocouples)
Capacitors have been incorporated into the input circuit to increase the noise elimination capability.
After voltage measurement, when the inputs have been disconnected, there will still be some electric
charge remaining. Before starting another measurement operation, short-circuit the + and - terminals to
enable self-discharge.
The MT100 has a scan system.
While in the status (open) in which signals are not input to the input terminal, measured results may be
influenced by signals from other channels.
In such a case, turn OFF the input setting or short circuit +/-.
If signals are input correctly, measured results are not influenced by other channels.
7. Noise Countermeasures
If the measurement values of the MT100 vary due to external noise, the following countermeasure is recommended.
(The effect varies depending on the noise type.)
Example 1: Connect the ground terminal of the MT100 to the ground (see the following figure).
Example 2: Connect the ground terminal of the MT100 and the ground terminal of a measurement
target (see the following figure).
Example 3: Set the filter to other setting than OFF in the AMP setup menu.
Example 4: Set a sampling interval at which the digital filter of the MT100 is effective (500ms or more).

CAUTION
8. Initial Setup
Language Setting
When you power on the MT100 for the first time after purchase, a language selection menu is displayed.
Select a language that you want to use.
The language setting can be changed later.
To change the setting later, open OTHR menu and select Language.
If you are using the MT100 for the first time, charge the internal rechargeable battery and then make the
date and time settings.
Setting the Date and Time
If the MT100 is not used for a period of approximately six months, the internal rechargeable battery may
be discharged and the date and time may revert to the initial settings. If this happens, recharge the
battery before using the MT100.
How to Recharge the Rechargeable Battery
Turn on the power switch and leave the MT100 connected for at least 24 hours.
How to Set the Date and Time
Press the MENU key, display the OTHR screen, and then set the date and time at the Date/Time Settings
sub-menu. Refer to the User's Manual in the supplied CD-ROM for more information on the setting.
