Please note:
(1) Press【AUTO RESET】for three seconds, display value is the time auto reset begins, i.e. “4” means auto reset starts
in 2 seconds (4/2=2) after the test; “6” means 3 seconds (6/2=3). To complete setting, press【ENTER】.
(2) Press ▲(increase) and ▼(decrease) to adjust to preferred value (note that is the value/2 is the actual seconds),
then press【ENTER】to complete the setting.
4. Press【UNIT】to select preferred one.
5. Press【SET】to set up maximum and minimum test result, press ▲(increase) and ▼ (decrease) to adjust value.
For example: when the LOWER light is on, enter 300 lbf.ft; when the UPPER light is on, enter 350 lbf.ft.
The LOW light will illuminate when test value is below 300 lbf.ft.
The HIGH light will illuminate when test value is above 350 lbf.ft.
The PASS light will illuminate when test value is between 300 lbf.ft and 350 lbf.ft.
※Green light outside black case will light up when test result passes.
6. To display B.P.M. value while testing, press【SET】and select B.P.M. function.
7. Press【SET】and select SET1 to set up testing duration (3~5 seconds recommended), press ▲(increase) and
▼(decrease) to adjust value.
8. Adjust test frequency【MODE FREQ】: Do not adjust unless necessary.
(1) Press【RUN MODE】and select preferred function: SHUT OFF / IMPULSE / IMPACT / TORQUE WRENCH.
(2) Press【MODE FREQ】and adjust frequency using ▲ and ▼. Press【ENTER】to complete.
Note: No need to adjust frequency value of【CCW】(anti-clockwise testing) and【TORQUE WRENCH】.
(3) Press【MODE FREQ】and adjust frequency using ▲ and ▼. Press【ENTER】to complete.
Note: No need to adjust frequency value of【CCW】(anti-clockwise testing) and【TORQUE WRENCH】.
9. 【CCW】lights up indicates anti-clockwise testing:
Press【CCW】until the screen displays signal（－）to do anti-clock testing.
Press【CCW】again,（－）signal will disappear.
※Red button on the black case is available for switching on/off CCW function.
Standard testing frequency value, please only adjust it when necessary.
【RUN MODE】Testing mode for each kind of tools:
IMPACT: Impact wrench
SHUT OFF TOOLS: Tools with clutch or auto shut-off upon reaching certain torque setting.
IMPULSE / CLUTCH TOOLS: Tools without clutch or auto-shut off function.
TORQUE WRENCH: Manual or digital torque wrench (applies to mechanical torque wrench only).
For testing dial indicating torque wrench or digital one, select【TORQUE WRENCH】function and press【AUTO REST】
to turn off auto reset.
Sensor accuray: > ± 0.3%
When test result exceeds maximum torque ranges of the sensor, display screen appears FFF, please stop immediately to
avoid further damage (sensor cannot be repaired once it is overload and damaged). Press【ZERO】or turn off the power
to restart.
Display may show FFF during pressing buttons due to data calculating, it can be disregarded. Just press【ZERO】.

Troubleshooting
When digital torque tester doesn’t work, turn off the power and restart. If still doesn’t work, follow below steps and
reset the system.
Step 1: Select unit as N-m.
Step 2: Use pointy tip to press【SET UP】, check and make sure if the value on display screen is the same as that
on the back board. If so, press【ENTER】to the next step; if not, adjust value using ▲ and ▼ until output number
matches, then press【ENTER】to the next setting.
Step 3: Check if the digits number after decimal point is correct, if so, press 【ENTER】to proceed to the next step;
if not, adjust value following Step 2. Then press【ENTER】to the next setting.
For example: a sensor with a rated torque (maximum torque) of 50 N-m ÷5000=0.01, it means that there must be 2
digits after the decimal point, the adjustment step is the same as 2, and the decimal point is moved to the correct
position, after setting, press【ENTER】once to proceed to next setting.
Step 4: Sensitivity check.
For example: the sensor with rated torque (maximum torque) of 500 N-m ÷ 5000=0.1, this 0.1 is the unit of minimum
count, the adjustment procedure is the same as 2, after setting, press【ENTER】once to enter next setting.
Step 5: Check if maximum torque value of the sensor is correct. If so, press【ENTER】to proceed to the next step;
if not, adjust value following Step 2. Then press【ENTER】to the next setting.
Step 6: Check if sample speed is set as 125 (out of three sample speed: 125, 250 and 500). Follow Step 2 to set up,
press【ENTER】after checking. Display screen will show 0.0, indicating the setting is complete.
During each step of setting above, if you would like to re-set any function, press 【ENTER】, turn off the power, turn the power
on, and proceed the setting you wish to do all over again.
If none of above-mention tips works and the problem can’t be solved after going through the steps, please return to SUMAKE
for further evaluation.
