FG-3000 Digital Force Gauge
Operation Manual
Operators should wear protection such as a mask and gloves in case
pieces or components break away from the unit under test.
Whether the unit is ON or OFF, DO NOT exceed the capacity of the
gauge. NEVER exceed 150% of the rated capacity, or the load cell will
be damaged. At 110% of the rated capacity, the display will flash a
warning.
When mounting FG-3000 Series Digital Force Gauges, use M6 mounting screws with a maximum insertion depth of 7 mm into the gauge.
Hand tighten mounting screws, DO NOT use tools. Do not use damaged clamp.
Measure in line tension and compression forces only. DO NOT attempt
to measure forces at an angle to the measuring shaft – damage to load
cell and/or shaft may result.
Do not attempt to repair or alter this instrument. Warranty will be voided
and damage to the unit may result.
Use and store within the stated temperature and humidity ranges, or
damage and failure may result.
When using adapter measuring heads, do not use tools. Hand tighten
only.

5.6 Calibration
Because of the sensor material performance or the influence of
external factors, there may be errors of a certain level after
a period of usage.
It is recommended to send the force gauge to a specialized testing organization for calibration.
If you have standard force weights or other standard load and a
test stand, you may utilize this function and procedure to calbrate
the sensor.
Fig. 5-6(a)
1) Mount the force gauge.
2) Use the tare by use of the ZERO key.
Fig. 5-6(d) Fig. 5-6(e)
5.7 Default
With this function, the force gauge can be restored back to the
original factory settings. Only perform this function when all other
troubleshooting tactics have first been attempted.
6. LANGUAGE
The force gauge can display in various languages. Set the language as desired. See Fig. 6.
3) Enter Calibration sub-menu as in Fig. 5-6(a).
The calibration interface is shown in Fig. 5-6(b).
Fig. 5-6(b)
4) Load a standard force. Now the value in the standard input area
is just equal to the current measured value. Wait a moment for the
force to stabilize.

7. INFO
Information about the force gauge such as model, version and
serial number is provided in this menu. Fig. 7

8. COMMUNICATION PORT
The force gauge has a USB for recharging and communicating
with a PC, plus an 8 pin connection for printer connection and set
point output. Fig. 8-1
5) Press ZERO and MODE to input the standard force value.
6) Press MENU to enter the next calibration. Press LOG to interrupt the calibration.
When 3 calibration points have been finished, a confirm window
will pop up asking to “Save and Exit”(YES)/(NO). Fig. 5-6(d)
Press ZERO or MODE to select, then press MENU.
If “YES” is selected, Calibration is complete. Fig. 5-6(e)

8.2 Setpoint Output
Two NPN open collector setpoint outputs are available.
The internal circuit of the setpoint output is shown as Fig 8-2.
Pin7 with Pin6 will be connected when an overload alarm occurs.
In Preset Mode, Pin7 to Pin6 is connected when the measured
value exceeds the upper limit. Pin4 to Pin6 is connected when the
measured value passes below the lower limit.
10. TROUBLESHOOTING
According to the following table, review possilbe solutions for
problems encountered. Do not disassemble the gauge by yourself or attempt to repair. If you cannot resolve the fault yourself,
please contact Nidec-Shimpo.
Failure Possible Causes Potential Solutions
Unit will not
turn on
No key
sound
No backlight Backlight is turned
Error is too
large
Low battery Recharge and then re-
boot. If after 3-4 hours of
charging time the battery
does not properly hold a
charge, the battery needs
to be replaced. Contact
Nidec-Shimpo.
Key sound is
turned off
off
The gauge is not
calibrated
Turn on the key sound in
menu
Turn on the backlight in
menu
Calibration of force gauge
is required. After calibration if the error remains
outside of the specifications, sensor may be
damaged. Contact NidecShimpo to get RMA for
return.
CAUTION: Maximum permissible voltage: pin 7 to 6, pin 4 to
6
must be lower than 35V ; pin 6 to 7, pin 6 to 4 must be lower
than 6V .
Remember to remove the load after measurement. Applying a
load for a long time period may affect the accuracy of the instrument.
9. MAINTENANCE
9.1 Maintenance
After use, please keep the instrument body clean. Do not let oil
and other substances persist on the body and screen so as not
to damage the instrument. Remember to remove the load after
measurement. Applying a load for a long time period may affect
the accuracy of the instrument.
9.2 Charging
When the battery is low, the icon “ ” will be displayed. The
batteries should be charged immediately.
Connect the gauge and the charger with the USB cable. Then
connect the charger with AC socket to start charging.
