Please Carefully Read This First
●Opera t ors shou ld wear protection such as a mask and gloves i n c a s e 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% o f th e ra ted capacity, or the load cel l will be damaged. At
110% of the rat ed capaci t y , the dis play wil l flash a warning.
●When mo unting the Digital Force Gauges, use M6 mounting screws with a
maximum insertion depth of 7 mm into the gauge.
●Hand tightens adapters, 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
shaf t m ay 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 hu m idity ra nges, or damage
and failure may result.
●If not using for extended periods of time, recharge it for every 2 to 3 months,
or remove the batteries to prevent potential batter y leakage from causing
product damage.

5.2 Calibration
Because of the sensor material performa nc e or the influence of
external factors, there may be errors in a certain range aft er a
period of time use.
Should send the force gauge to a specialized testing organization
for calibration.
If you have some stansard force weights or the other standard load
and some test stand, you may calibrate it also.
① Mount the force gauge.
② Remove the tare by use of the key .
③ Enter C alibration interfac e, as Fig 5-2.
The calibration interface is shown as Fig 5-3.
④ Load a standard force.Now the value in
standard input area is just equal to the current measured value.Wait a moment for the force stability.
⑤ Touch and to input the stansard force value.
❶Calibration times
❷Current measuring value
❸Standard value input

⑥ Touch to enter the next calibration. Touch can interrupt the calibration.
When the 5 times calibration had been finished or be interrupted, a confirm window will pop up to ask
for save or not save the calibration. (Fig. 5-3)
Touch or to sel ect, the n press .
If "YES" is selec te d , "Calibrate complete!" is displayed.
NOTE:
①Set the unit of force to the unit used in calibration previously(as shown in 3.2.1 Unit)
②Ensure that the tare weight of attachment has been remove before calibration.
③You can do any point or points calibration from 1 to 5 point., we recommend 5 points calibration.
