6. Explanation of each feature
6.1. Auto zero
In the RUN mode, press
key, and auto zero adjustment works.
If the displayed torque is more than 7.5 of the maximum capacity torque, the display shows
"Err9".
<Display shows “Err9”>
Press
key without torque load.
If “Err9” disappears, this instrument can be used normally.
If not, press reset key and
key once again.
6.2. Error message
<Err 1 to 5> Error in membrane switch
Turn off the power once and turn it on again without touching any keys.
-If error disappears, then is operates normally.
-If not, contact TOHNICHI or the nearest distributor to ask for repair.
<Err 8> Error in data memory
Contact TOHNICHI or the nearest distributor to ask for repair.
<Err 9> Error in the circuit board or the torque sensor
At no load condition, press
key.
-If “Err9” disappears, then it operates normally.
-If not, contact TOHNICHI or the nearest distributor to ask for repair.
6.3. Auto memory/ reset
After tightening or measuring, the values are automatically saved and forward to the counter to
the next. Auto memory timing can be selected from 0.1 to 5 seconds.
If you do not want to use auto memory function, set it as 0.0 seconds.
6.4. Judgment
Set the lower and higher limit torques, these judge whether the measured result are within the
range or not.
Under the Tightening mode (MODE-T), when you set the high/ low torque and angle, double
tightening detection angle, and direction of tightening, the tool gives the beep intermittent and
blue LED if the torque value reaches about 80% of low limit torque. Once reaches on low limit
torque value the tool give beep continuous and red LED.
Under the Inspection mode (MODE-M), if you set the high and low limit torque values the tool
makes judgment the measured torque result.
If you set the Auto memory/ reset, the judgment is made automatically.
