HANDHELD FORCE GAUGE
User Manual - HFG 50
Type: HFG-50
The HFG-50 50N capacity Handy Force Gauge is an accurate, high-quality instrument,
it was developed for simple and accurate measurement of contact compression force
on test probes kept in hand or mounted on a support. It is also suitable for tension
force measuring.
Operation features:
•Small, lightweight,handheld, fits in pocket,
•Strain gauge load cell system for accurate force measurement,
•High grade amplifier for strain gauge bridge,
•Programmable microprocessor controlled,
•Easy to read 3 digit LCD display with large numbers,
•Hold function for displaying the maximum force,
•Low voltage warning : LoBat,
•Operating voltage: 9V DC –battery or rechargeable accu,
•Alarm signal at overload, at 120% of full scale (60N),
•LED display for tension load signaling,
•Automatic switch-off in 30 seconds if the force is under 1N,
•Robust case, the cabinet load free, when mounted on a support (test stand),
•High durability: more, than 1.000.000 cycles,
•Foil keyboard with 2 keys,
•Lead free soldering construction,
•Easy installation and handling, calibrated, (available Test Report).

Operation:
Switch on: press the null key for 1 second, Cont will be displayed. Press null key for 2 seconds,
and the instrument will be in continuous measuring mode. Press the null key for zeroing the
display, then 0.00N will be displayed and start measuring.
Hold function: press the set/hold key, the display is: Hold, then press the null key, then the
instrument will be in Hold measuring mode. Press the null key for zeroing display then 0.00N
will be displayed. Now you can measure. In hold function you can measure the maximum value
(peak) of the applied force. If you apply more load, the instrument displays and holds this new
maximum value. For starting new measure press the null key for zeroing display, then 0.00N
will be displayed and start measuring.
Continuous measuring function: press the set/hold key, until the
display is: Cont , then press the null key, then the instrument will
be in Continuous measuring mode. Press the null key for zeroing
the display, then 0.00N will be displayed and start measuring.
Switch off: press the set/hold key, until Off will be displayed then
press null key so the instrument is switching off, or put the
instrument down, and it will automatically switch off in 30 seconds,
when the displayed force is under 1N.
For mounting to the holding support (test stand), use 2pcs. M4 screws,
Min.length of screws =support thickness + 7mm,
Max. length of screws=support thickness+11mm, no longer!
