Tension Measurement
To measure tensile force, use the hook attachment. The
display will show the force measured and a minus sign (-)
will appear on the left of the display (to the left of the
digits).
NOTE: To display no sign (plus) for tensile force, consult
the “Function Setting” section.
Compression Measurement
To measure compression force, use the flat head
attachment. No sign will appear on the left of the display
during a compression measurement.
NOTE: To display minus sign (-) for compression force,
consult the “Function Setting” section.
Low Battery
When battery charge is low, LO BAT will appear on the
display indicating the batteries need to be charged.
Charging time of fully depleted batteries is approximately
18 hours when the unit is off. The adapter/charger
automatically shuts off when the battery is at full charge
to protect the battery.
NOTE: The adapter/charger can be used to power the unit
during battery charging, but will lengthen charging time.
Auto Power Off
If the gauge is on and there is no activity for 10 minutes,
the unit automatically powers off to conserve battery
charge. PWR appears above the display digits to notify
that there is 1 minute before power off. If the adapter/
charger is powering the gauge, auto power off function
becomes inactive.
NOTE: To modify the auto power off function, consult
the “Function Setting” section.
External Device Communications
When operated with the appropriate output cable, the
FGV-HX offers output capabilities.
Overload
Caution should be exercised that overloads do not occur;
sensor damage can result. To protect the gauge and
sample under test when used with a motorized stand
(or similar device), two built-in OC NPN transistors stop
motion when the gauge reaches 120% of its rated
capacity. One transistor is for tension, the other for
compression (figure 2).
Analog Output
An analog output signal is available for recording
purposes. The amplitude of this signal is ± 1 VDC. The
voltage is positive when compression testing is performed
and negative for tension. The signal characteristics are
as follows:

NOTE: When the zero switch is pressed to tare the gauge
the analog output goes to 0V automatically.
