The new FG-3000R Series digital force gauges are the choice for 

simple, cost-effective compression testing. Combining one of the 

most compact housings, yet maintaining a large back-lit LCD, 

these units were designed to fit perfectly in the hand for ease of 

use.  The multi-language FG-3000’s provide menu programming 

for intuitive set-up of the instrument to your desired requirements. 

Three modes of operation are selectable: Track mode displays 

live readings, Peak mode records the maximum reading sensed 

during the test, and Pre-set mode which activates user defined 

high and low limit set points. The programmable limits provide a 

quick visual and audible indication if a test passes or fails.  In ad-

dition, a comparator output enables integration of the instrument 

into your quality system for repetitive testing such as on produc-

tion lines. 

The integral button style load-cell attached via the flexible, metal 

braided cable enables reading to be taken in machinery or fix-

tures where other force gauge adapters are unable to reach or fit.

The display graphics facilitate user comprehension and opera-

tion.  An analog bar graph provides perspective of current reading 

in comparison to the full scale range.  Pass/Fail icons provide an 

instant response of the testing outcome while a storage symbol 

acknowledges when a reading is logged.  A menu-selectable dis-

play orientation streamlines switching from push to pull testing for 

portable or test stand applications.

FG-3000R 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 M4 mount-

ing 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.
