Connection Procedures
Connecting the AC Adapter
Connect the DC output of the AC adapter to the
connector indicated as "DC LINE" on the GL980.
Connecting the Grounding Cable
Use a flathead screwdriver to push the button above
the GND terminal while connecting the grounding
cable to the GL980. Connect the other end of the
cable to ground.

Precautions to Observe When Taking Measurement
To avoid break-downs or short-circuiting accidents, please make sure to follow warnings written
below.
• Use only the AC adapter provided as a standard accessory. The rated power supply range for the adapter is 100 to
240 VAC, and the rated frequency is 50/60 Hz. Do not use any other voltages.
• Do not input the voltage that exceeds the specification of this device.
∙ If a voltage exceeding the specified value is input, the semiconductor relay in the input section will be damaged.
Never input a voltage exceeding the specified value even for a moment. It will cause fire.
∙ Have enough margin from the specification of withstanding voltage when using this device, it has to consider a
noise and change of the measurement voltage.
∙ Confirm this device is not broken before the input cable is connected to the input terminal.
∙ Please take care of the static electricity when connecting the input cables or the thermocouples.
∙ Do not touch the tip of thermocouples with bare hand after the thermocouples are connected to the terminal of this
device when the tip is not insulated.
The static electricity from a human body will cause damage to the device.
∙ Do not put the tip of thermocouples to an object which contains static electricity when the tip is not insulated.
The static electricity from object will cause damage to the device.
∙ Do not put the tip of thermocouples to the object which contains leaked high voltage from chassis or metal etc.
when the tip is not insulated.
The leaked high voltage from object will cause damage to this device.
∙ We recommend that an insulation tape is placed on the tip of thermocouples before connecting it to the input
terminals.
This will protect the device from the static electricity and the leaked high voltage.
• To prevent electric shock and short circuit accident, do not connect to BNC terminal and screw terminal at the same
time.
When using
Please be sure to read the following carefully in order to prevent electric shocks or short circuit.
•
Maximum input voltage
If a voltage exceeding the specified value is input, the parts in the input area will be damaged.
Never input a voltage exceeding the specified value even for a moment.
< Between +/– terminals A >
• Maximum input voltage: Range of 20mV to 2V : ±30V
Range of 5V to 500V : ±500V
<Between input terminal and input terminal B >
Maximum input voltage: 60Vp-p
Withstand voltage: 1000Vp-p at 1 minute

For example, when you are using a 4GB SD card with 100MB already used, the total capacity of the SD card is
4GB with 100MB used space, and the available space of the SD card would be approximately 3.9GB. As the
captured time elapses, the usage of the SD card increases and the remaining capacity of the SD card
decreases.
The remaining recording time indicates the remaining capacity of the SD card.
However, when the relay capturing function is set to Off, and when the remaining capacity of the SD card
exceeds 4GB, the remaining time that can be captured to 1 file will indicate 4GB.

1. When recording stops, it automatically switches to recorded data playback.
To check the recorded data value press the direction keys to change the CH and
the cursor. Pressing the fast forward key will move the cursor at high speed.
2. If you press the [MENU] key during playback, you can search for
playback data and calculate between cursors.

Maximum input voltage : 0 to +30V (single-ended ground input)
Input threshold voltage : Approx. +2.5V (logic input, pulse input)
Approx. +1.9V (external trigger, external sampling)
Hysteresis : Approx. 0.5V (+2.5V to +3.0V) (Logic input, pulse input)
Approx. 0.2V (+1.9V to +2.1V) (external trigger, external sampling)
Output format: Open collector output (5 V, pull-up resistance 10 kΩ)
Contact capacity 5V to 24V, 100mA or less (0.2W or less)
Output conditions: Level judgment, window judgment, logic pattern
judgment, pulse judgment
Trigger output
When a trigger is detected after trigger output is set, a pulse of approx.
500 μs width is output from the Output 1 terminal. (Low active)
Pulse input
Pulse sampling interval: 10 μs to 1h
* Set it separately from sampling interval.
Setting faster than sampling interval is not possible (constant multiple)
Revolutions mode (engines, etc.)
Function: Mode to convert to the number of revolutions per minute by applying magnification
after counting the number of pulses for each pulse sampling interval.
Span: 10 to 500M
Counts mode (electric meters, etc.)
Function: Mode to accumulate the number of pulses for each pulse sampling interval from
the start of measurement
Span: Automatic (Maximum 20M)
Inst. mode
Function: Mode to display the number of pulses for each pulse sampling interval.
The accumulated value for each pulse sampling interval is reset.
Span: 10 to 20M
Maximum number of pulse inputs
Maximum input frequency : 100 kHz
Maximum number of count : 15 MC (24-bit counter)
External sampling input
Maximum input frequency: 100 kHz
Temporal error: 1 μs or less.
