1-2. Display Procedure of A channel, B channel and 2 channel
G1000 performs the A/D conversion of analog input signal from strain gauge sensor and displacement
sensor, then does calibration and scaling, after that, displays the result as indicated value, finally
compare with comparison set-values and outputs the results.
In addition, for calibration, scaling, comparison set-values etc., it can be saved up to 16 patterns, and
can be switched by pattern select signal or RS- easily.
1) Connect lines
Connect the sensor, I/O signal, RS-232C, RS-485, analog output, BCD output, etc.
・please refer to「3. Terminal Connections and Description」.
2) Do basic function setting
・please refer to「6. Basic Function Setting (Setup)」.
3) Do calibration. (Do each of Ach and Bch individually.)
・please refer to「7. Strain Gauge 」.
4) Set and finalize each itemized setting.
・please refer to「5-4. Data Setting Tree」
5) Check if item is displayed as set-value.
1-3. Procedure of Waveform Display and Hold Function
Using set-values in graph display, to detect some parts of the analog input waveform (e.g. the peak, the
valley, the maximal, the minimal, inflection point), perform the comparison and output the result.
For hold type setting in hold function, comparison set-values, graph display setting, it can be saved up
to 16 patterns, and can be switched by pattern select signal or RS- easily.
1) The procedure from line connection to calibration is the same as above-mentioned.
2) Perform each operation and setting.
・Please refer to「8. Operation of Waveform Display」.
・Please refer to「11. Hold Function (Hold)」,「13. Graphic Display Setting (Graph Disp)」.
3) Operate the input signals STA, STB, START, RESET, STOP and confirm the display and action.
1-4. Procedure of Waveform Comparison / Waveform & Displacement Comparison
Waveform comparison is, perform the A/D conversion of the analog input waveform which changes with
time or displacement, compare the converted value (indicated value) with HI/LO limit waveform
set-values, then output the result.
For HI/LO limit waveform set-values, comparison range, HI/LO limit displacement set-values, it can be
saved up to 8 patterns, and can be switched by pattern select signal or RS- easily.
1) Perform each operation and setting.
・please refer to「12. Waveform Comparison / Waveform & Displacement Comparison (Waveform)」.
・please refer to「11. Hold Function (Hold)」,「13. Graphic Display Setting (Graph Disp)」.

1) Outside dimensions
[Front] [Side]
[Rear] [Panel cutting hole]
*When you have no memory card function, there is no SD cover of the front upper part.

2) Mounting method
Make a mounting hole shown by the panel cutting hole and remove the mounting bracket from the
rear side. Fit the body from the front side of the panel as shown in Fig. below, and tighten the
mounting bracket from the rear side.
Top surface
Mounting brackets
(upper and lower sides)
Body (aluminum case)
(1)Panel board thickness is 1 to 5mm. Use tightening torque of about 0.39 N･m.
(2)Do not locate the Meter in a place where ambient temperature is outside the range of 0 to 40℃,
humidity is outside the range of 35 to 85 % and humidity changes suddenly, causing dew
condensation.
(3)Use the Meter in a place free from dust, dirt, chemicals and corrosive gases harmful to the electric
parts.
(4)Protect the Meter from any vibration and shock.
(5)When locating the Meter in facilities, use care to radiate heat so that temperature inside the
facilities may not exceed 40℃.

Screw terminal for I/O units
(*Cautions)
RS-232C connector
Power-supply
terminal
Touch-panel color LCD display
Power indicator
*Cautions : Use the screw terminal for I/O units at the time of analog output or RS-485.
Use a connector of card edge type ribbon cable at the time of BCD output, instead of the
Conforming cable : UL2651 AWG#28 flat cable (7 cables/0.127mm, cable shield diameter 0.8
to 1.0mm)
When you have no memory card function, there is no SD cover of the front upper part.
3-1. Connection of Power Supply
・AC input voltage is 100 to 240V AC ±10％(50/60Hz).
・DC input voltage is 24V DC ±15%.
・Connect power supply to terminals No.1 and terminal No.2 (N).
・Terminals No.3 ( )and terminal No.4 ( ) are connected with a
short bar.
・Ground it to prevent an electric shock and a trouble of static
electricity.
・As Terminal No.3 is charged at neutral point, use care to prevent it
from contacting other terminals.
・Terminal No.4 is connected to the frame (case). It can be used for
noise countermeasures and to prevent the trouble of static
electricity in an environment where no grounding is available.
・terminal is a protective earth terminal. It has the same
electric potential as No.4 ( ).

・Four-wire type ・Six-wire type
・Before connecting the sensor, set power-supply voltage (Sensor
power) to the sensor and turn off power to this Meter.
(please refer to「7-1. 4) Sensor power」. )
・Terminals (4) to (7) are for input of Ach.
・Connect the shield (shielding wire) of the sensor to the frame
ground.(FG)
・When connecting a six-wire type strain
gauge sensor, short-circuit (+ EXC and +S)
(-EXC and -S), respectively.
Other connections are the same as those
for four-wire type.
Cautions！
Applied voltages to the strain gauge sensor are 2.5V, 5V, and 10V.
When any sensor rated below the applied voltage is connected, it may generate heat or be damaged.
