Torque Meter Operating Method (Tools: Torque Meter, Automatic Electric Screwdriver)
A
.Choose a proper electric screwdriver type in accordance with the required torque of screw-fastening. Please consult
with electric screwdriver catalogue or vector chart of electric screwdriver
B
.Choose a proper Torque Meter: KTM-15 can be measured torque at maximum 15 kgf.cm ; KTM-150 can be measured
torque at maximum 150 kgf.cm; KTM-250 can be measured torque at maximum 250 kgf.cm select the Screw Joint
(According to the basis of requiring torque measurement which can be parted with 6 items as following tables:

Test procedures:
1.Switch on the power
2.Set measure mode (MODE) to “TRACK”
3.Unit switch sets to required measurement of unit. (lbf.in
；

；
N.m)
D
.
Reset adjustment: Check the value on LCD display if is at zero status, if not then press CLEAR to display 0.0.
E.
Set measure mode (MODE) to “PEAK”.
F
.Cover with connecting pole of Screw Joint on the electric screwdriver, put another end of connecting pole in the head
terminal of Screw Joint, power on the electric screwdriver and start to measure output torque of the electric
screwdriver.
G
.When torque value has been indicated, it means functional measurement for electric screwdriver is normal and
accomplished; the value indicates on LCD display is the output torque value of electric screwdriver.
H
.After finishing the measurement of electric screwdriver, reverse to loose Screw Joint for keeping from springiness
fatigue.
I
. Use the same electric screwdriver on different brands of Torque Meters (or Screw Joint) could result in different
torque value inaccuracy, such inaccuracy comes mostly from different spring character of Screw Joint. If there are
two sets or more Torque Meters using on the work site, responsible department should examine Torque Meters
periodically and check the gap of spring character among those Screw Joint whether too large, if the answer is yes,
then need to change a new spring or the whole set of Screw Joint.
J
.Please note while using Torque Meter, don’t charge the battery at the same time in order to avoid affecting the
accuracy of test data.
