四. 準備與測量方法
4-1 安裝
測量儀器在測量較大扭力時可能會揮動起來。因此測量儀器必須用穩固的腳座器具來固定它。
4-2 測量模式的設定
有以下兩種模式可供選擇。(視使用用途來選擇)
(1) P-P(PEAK) 峰值模式：顯示測量到的最大扭力值。
(2) TRACK 變值模式：顯示即時的扭力值。
(3) P-D(PEAK DOWN) 初值模式：顯示第一個峰值。
4-3 測量方式(在有使用彈簧座時)
(1) 歸零調整: 打開扭力計電源，再將測量模式切換到＂TRACK＂，此時顯示器的數值應為零。若不是零則按＂
歸零開關＂將數值歸零，接著將測量模式切換為＂PEAK＂ 。
(2) 將彈簧座安放在扭力計的測試底座上(20 方形) 。
(3) 準備好受測工具並銜接適合的接桿，將接桿與彈簧座垂直接合即可進行扭力測量。
(4) 測量時應順時針將彈簧座完全鎖緊或工具自行停止或跳脫為止。
(5) 當測量完成後，顯示器上的數值就是該次測量的扭力值。
(6) 如果要再進行測量，要先將彈簧座反時針放鬆，並在再次測量前按＂歸零開關＂將顯示器的數據清除。
(7) 儀器在連續 10 分鐘未使用的情況下，將會自動關機。
4-4 自動歸零的設定
(1) 在關機的情況下，一手按著＂歸零開關＂不放，一手按＂電源開關＂將儀器電源打開，在打開電源後便放開＂
歸零開關。
(2) 此時顯示器會顯示＂-.-C＂，若無則重複步驟(1)。
(3) 按＂歸零開關＂以改變顯示值，亦即改變自動歸零的時間；顯示值最低為 0.0 秒，最高為 3.0 秒，當顯示 0.0
秒時表示取消自動歸零的功能。設定秒數後靜待數秒，儀器會自動進入待測狀態。
五. 充電
當顯示器上出現＂LOBAT＂字樣時表示扭力計電量不足，需進行充電。
請關閉扭力計電源，以隨機配備的充電器，接妥正確電源與扭力計充電孔即可進行充電。
充電時間請勿超過 8 小時，以免造成電池過熱、漏液甚至燃燒等傷害。
六. 數據傳輸
數據傳輸(需搭配專用傳輸線與軟體) : 在每次測量完畢按歸零開關時(或機器自動歸零時)，扭力計會自動將測得
的數據經傳輸裝置輸出到電腦上。
※ 搭配用的傳輸裝置為選購產品。
七.系統重置
當電池的電量完全耗盡或儀器在長時間沒有使用下，重新充電開機時會有無法動作的情況，此時可嘗試觸動＇系
統重置(System Reset)＇開關，將系統重新回復到出廠時的設定，但先前的所有設定將完全被清除。

十. 電動起子與扭力計
1．電動起子之扭力調整
a. 旋轉扭力調整環以增加或減少扭力輸出。
順時針方向調至較高刻度，代表增加扭力；逆時針方向調至較低刻度，代表減少扭力。
b. 操作電動起子時應循序漸進，先操作小扭力試鎖螺絲，若感覺扭力不足再漸漸調高扭力。
c. 電動起子的扭力輸出和扭力刻度的相互關係可參考說明書內的＂扭力曲線圖＂。
鎖緊螺絲之扭力大小取決於螺絲本身之型式、材質尺寸及其鉚合物之材質。
d.當被鎖物件鎖附完成時，視其符合品質標準後，再用扭力計測量該電動起子的正確扭力，若鎖附狀況未達標
準，則調整電動起子扭力，直到符合標準為止。
e. 電動起子用扭力計測量並記錄好扭力後，將起子外殼前鎖環旋開，換上扭力固定環，如此可以防止異常的扭
力變動。
2、扭力計的使用方法（工具：扭力計、全自動電動起子）
a. 根據螺絲鎖附所需要的扭力選擇適當的電動起子型號，
可參考電動起子目錄或電動起子向量圖表
b. 選擇合適的扭力計: KTM-8 最大可測扭力為 10Kgf-cm，KTM-80 可測最大扭力為 100 Kgf-cm；選擇扭力計彈簧
座（依欲測試的扭力為準可分為三種，請參考以下表格）。
使用範圍(Kgf-cm) 扭力計 彈簧座 備註
3.0 以下 KTM-8 SJ-3 最大可測 3Kgf-cm
KTM-8 SJ-10N
3.0~10.0 KTM-80 SJ-10 最大可測 10Kgf-cm
10.0~50.0 KTM-80 SJ-50 最大可測 50Kgf-cm
c. 測試步驟：
1打開電源開關。
2測量模式（MODE）設定為“TRACK＂ 。
3單位切換開關設定為欲測試的單位（Lbf-in；Kgf-cm；N-m）。
d. 歸零調整: 檢視顯示器數值是否為歸零狀態，若不是則按歸零開關（Reset），使顯示歸零。
e. 測量模式(MODE)設定為“ PEAK＂。
f. 電動起子套上接桿，另一端則置於彈簧座接頭端，啟動電動起子開始測量電動起子輸出扭力。
g. 當數值顯示後即表示電動起子測量正常與完成；顯示器上的數值就是電動起子輸出扭力值。
h. 完成電動起子測定後，需反轉放鬆彈簧座，以防止彈簧座彈性疲乏，按歸零開關清除螢幕後即可繼續測量。
i. 使用同一把電動起子於不同廠牌型號的扭力計（或扭力計彈簧座）會產生不同的扭力值誤差，其誤差來源多
為彈簧座的彈簧特性不同所致。同一工作場所有兩台以上的扭力計時，使用單位應定期校驗扭力計並比對其
彈簧座的彈簧特性差異是否過大，若差異過大則應替換新的彈簧或整組彈簧座。
j. 使用扭力計時請勿同時進行充電，以免影響測試數據的準確性。

4. Preparation and the measuring method
4.1 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.
4.2 A setup in the measurement mode
The 3 following modes can be chosen with the setting. (It unites with the use purpose
and please choose.)
(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 (peakdown measurement) : Value when load torque value changes from a rise to descent is displayed.
Carry out after pushing a CLEAR button at once when applying re-load.
*PD and PP measurement operates from 10 or more numerical values.
4.3 Measuring method (at the time of screw joint use)
(1) Check that the display part is zero at the time of power supply ON. If display is not show as zero,set a measurement mode select switch to
TRACK, push CLEAR button,and set it as back PP which performed zero adjustment.
(2) Set screw joint to the socket part (20mm square) of torque meter.
(3) The bit of screwdriver to measure among the screw part of screw joint is set firmly, and screwdriver is started.
(4) 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.
(5) After a measurement end, if CLEAR button is pushed, a display will be cleared by zero.When continuing measurement, it repeats from (1) again.
4.4 Display – timer set function (a measurement display is reset zero by time.)
Timer Set method
(1) The power supply SW is changed into the state of OFF.
(2) While pressing down a CLEAR button, press a power supply SW –one shot aggressiveness.
IF a display appears in a LCD, release a CLEAR button.
(3) If a CLEAR button is pushed while displaying it as ｀-.-C＇, auto clear time will change and will be displayed. Choose clear time. When you
cannot set within 3 seconds,operate it from (1) again. (0.0 C display is manual)
clear time selection 0.0 C →0.1C→ 0.5 C → 1.0 C (seconds)
↑ ↓
3.0 C ← 2.5 C ← 2.0C←1.5 C
5. 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 supply 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 for about 1 second.

10. Checkpoint when being Troubled
- Before judging it as failure -
When functional fault arises, please check based on a table, without judging it as failure immediately. By the corresponding processing, when fault is
not canceled, please tell repair to our company or a store.
In addition, it is allowed to make the guarantee term of torque tester into one year from a purchase. However, also in an onerous case, it is according
to the contents of repair.
The situation of torque tester It does not hold by measurement mode PP-PD.
The cause of generating It is used by setting up an auto clearance.
The processing method Please check the setting item of an auto clear function again.
When you do not use an auto clearance, please set it as 0.0C.
The situation of torque tester Even if it turns on a power-supply switch, a power supply will go out immediately after LOBAT display.
The cause of generating Charge is insufficient.
The processing method Regular time charge is carried out using the exclusive charger appended.
The situation of torque tester Even if it turns on a power supply after charge of regulation time, it does not display.
The cause of generating If it is not used for a long period of time, internal battery will carry out full electric discharge.
The processing method If AC adapter is connected and the S.RESET button of the side is pushed, it will return. After a return, please make
a measurement mode switch the position of TR, push a clear button and make a display into zero.
11. How to deal with joint
The new type joint which added the function to prevent that a bolt and a base separateto old joint is appended.
By attaching the screw which prevents that a bolt separates,it races at the same time a bolt separates from a base, and it does not decompose.
However, since you may wear a screw mountain out and torque value may change when it continues racing, please be careful.
Moreover, if it is left where a spring is closed when there are wear, a metal fatigue, etc.of a screw part, a bolt may jump out with the pressure.It is the
new joint equipped also with the dangerous prevention in that case. (PAT,P)
The cautions on use
* Please do not apply the load more than the measurement range by any means.
* Attached grease is attached to the bolt or the bearing part, please check before use.
* Where a spring is loosened, please be sure to keep after use.
The number of times of an exchange standard is about 2500 times.
When the following condition comes out, please stop use, and use new joint.
When there is bend and wear of a screw thread
When there is sound etc.
For any inquiry, please contact your dealer !
