Preparation and the measuring method
Installation
A measuring instrument may be brandished at the time of measurement of a large torque. Surely, a measuring
instrument should use a fixed knob etc. and fix it firmly.
A setup in the measurement mode
The 3 following modes can be chosen with the setting to meet user's testing requirement.
①
PP (peak measurement): The maximum under measurement is always displayed.
②
TRACK (track measurement): The value of the load torque concerning the detection machine is displayed as it is.
③
PD (peak down measurement) : Value when load torque value changes from a rise to descent is displayed.
Carry out after pressing a CLEAR button at once when applying re-load.
※
PD and PP measurement operates from 10 or more numerical values.
Measuring method
④
Check that the display part is zero at the time of power ON. If display is not show as zero, set a measurement mode
select switch to TRACK, press CLEAR button, and set it as back PP which performed zero adjustment.
⑤
The bit of screwdriver to measure among the screw part of screw joint is set firmly, and screwdriver is started.
⑥
It checks that operation of screwdriver has been completed normally, the measurement torque value of a display
part is read, and it becomes a measurement end.
⑦
After a measurement end, if CLEAR button is pushed, a display will be cleared by zero.
When continuing measurement, it repeats from

again.
⑧
Choose the TRACK mode, if real time torque value wants to be measured.

Power supply
If this measuring instrument is left 10 minutes or more or battery capacity stops being sufficient, a power supply is
turned off automatically. If battery capacity decreases, since LOBAT will be displayed, charge by inserting the
connector of an exclusive charger in an AC ADAPTOR terminal.
The fully charge is in the state which turned OFF the power switch, and takes about 8 hours.
(Do not perform charge of 8 hours or more. It may become the cause of the fire by a burst of a battery, generation of
heat, and liquid leak, or an injury by fault charge.)
Moreover, when turning off a power supply, a power supply SW is pushed about 1 second.

System Reset
CPU in the tester might not start even if the battery charges it with electricity complete discharged.
(When not using it for a long time.)
In that case, an AC/DC adaptor is connected and a system reset button is pushed.
It will be in an initial state (all the contents of memory are eliminated).
Do not use Reset except the following conditions.
※
When the display doesn't appear even if this machine is not used for a long time and charged.
※
Additionally, when the tester doesn't work.
Since all the contents of memory are eliminated when system reset is performed, redo a setup once again.

Guarantee
It is allowed to fix gratuitously, if the fault which will originate in manufacture, transportation, etc. of our company
within one year after a purchase should occur, although product was manufactured under sufficient quality control.
In the following case, it becomes the charge also within a guarantee term.
Failure by the error, and unjust repair and unjust reconstruction and damage on use Failure by fall etc. and damage after
a purchase.
Failure by the natural disaster, pollution, and unusual voltage, and damage.
