7-1.Set measurement mode (Initial Setting: TRACK)・You can switch the measurement mode.
Switch between TRACK mode and PEAK mode by pressing the "DAT" switch.
The one with a black background is the one selected.
TRACK: The torque value applied to the detector is displayed as it is.
It is used to view measurements that change constantly.

"DAT" Switch

PEAK： Hold and display the maximum absolute value during
measurement. Hold a torque value from 0.2% or more of the
maximum measured value of each model.
"DAT" Switch

PP： The screen will be displayed in two sections.
Centering on zero, the upper section is the + peak holding and thelower section is the - peak holding. Both hold a torque value from
0.2% or more of the maximum measured value of each model.
"DAT" Switch* Short press the "FUN" switch to confirm the setting. Next is the setting for changing measuring unit.

7-2.Change measuring unit (Initial Unit： N・m or N・cm)
・You can change the measurement unit.
Switchable 3 units: N･m(N･cm), kgf･cm(gf･cm), lbf･in* The unit symbol changes depending on the model.
"POW" Switch"POW" Switch"POW" Switch* Short press the "FUN" switch to confirm the setting. Next is the setting for comparator HI.

7-3.Set comparator HI (Initial value: 0000)〇 TRACK / PEAK Mode
・You can change the HI side setting value of the comparator.
A comparator is a comparison with a set value.
For example, if you set the point of high value (HI) to 1.00N･m and the point of low value (LO) to 0.50N･m
and gradually apply force from 0.00N･m, LO will be indicated with a long intermittent sound at first,
but the display and buzzer sound will disappear when the force exceeds 0.50N･m.
When the force exceeds 1.00N･m, HI will be indicated and a short intermittent sound will be heard.
* When the HI or LO value is set (non-zero), the external output is also outputted in conjunction with it.
* The setting value should be entered as an absolute value (regardless of whether it is positive or negative).
"DAT" Switch

The digit shifts to theleft by one place
every time the"DAT" switch ispressed.

This digit blinks.

"DAT" Switch"DAT" Switch

This digit blinks whenthe "DAT" switch ispressed 3 times.

* It returns to the beginning when the "DAT" switch is pressed 4 times.

"POW" Switch"POW" Switch"POW" Switch

The value will increase if the"POW" switch is pressed
while this digit is blinking.

"9" is indicated when the "POW"
switch is pressed 9 times.
It returns “0” when the "POW" switch
is pressed again.

〇 PP Mode
・You can change the setting value on the + side (upper section) of comparator.
For example, if you set the point of + side (HI) to 1.00N･m and the point of - side (LO) to -0.50N･m, andgradually apply force to the + side from 0.00N･m, the display of the upper section will be changed, andwhen the force exceeds 1.00N･m, a short intermittent sound will be heard.
* The setting value should be entered as the value of + side instead of an absolute value.
* A short intermittent sound will be heard if the HI setting value (+ side) is exceeded, and a long one if the LO
setting value (- side) is exceeded. After that, even if the HI peak value is exceeded, a long intermittent soundcontinues.
* A long intermittent sound will be heard if the LO setting value (- side) is exceeded, and a short one if the HI
setting value (+ side) is exceeded. After that, even if the LO peak value is exceeded, there is still a shortintermittent sound.
* The position of the decimal point varies with each unit and each model.
* For models that increase in digits, the maximum setting value is 9999.
For example: When the unit is N・m in AD-TM100, the settable maximum value is 9.999(N・m).
* The setting value returns 0 when the mode is changed.
* Short press the "FUN" switch to confirm the setting. Next is the setting for comparator LO.

7-4.Set comparator LO (Initial value: 0000)〇 TRACK / PEACK Mode
・You can change the setting value on the LO side of comparator.
・Refer to 7-3. Set comparator HI for the function description, setting method, and operation method.
〇 PP Mode
・You can change the setting value on the - side (lower section) of comparator.
For example, if you set the point of + side (HI) to 1.00 N･m and the point of - side (LO) to -0.50 N･m, andgradually apply force to the - side from 0.00N･m, the display of the lower section will be changed, andwhen the force exceeds -0.50N･m, a short intermittent sound will be heard.
* The setting value should be entered as the value of - side instead of a absolute value.
* A short intermittent sound will be heard if the HI setting value (+ side) is exceeded, and a long one if the LO
setting value (- side) is exceeded. After that, even if the HI peak value is exceeded, there is still a longintermittent sound.
* A long intermittent sound will be heard if the LO setting value (- side) is exceeded, and a short one if the HI
setting value (+ side) is exceeded. After that, even if the LO peak value is exceeded, there is still a shortintermittent sound.
* The position of the decimal point varies with each unit and each model.
* For models that increase in digits, the maximum setting value is 9999.
For example: When the unit is N・m in AD-TM100, the settable maximum value is -9.999(N・m).
* The setting value returns 0 when the mode is changed.
* Short press the "FUN" switch to confirm the setting. Next is the setting for overload.

7-5.Set overload OV (Initial value: 120)
・It is a function to warn the users to avoid accidental damage to the torque sensor.
For example, when performing a torque test, it can display a warning at 80% of full scale and output a signal
to stop the test so that the sensor is not damaged by applying excessive force accidentally.
* The setting can be set by 10% up to 120%.

External devices

F.G. shielded wire

* Voltage: ± 2V to the max.
* Please use an analog earphone jack (with shield) for connection to external devices.
* Do not short circuit. It may cause a malfunction.
* Do not apply voltage from outside.

12.Digimatic communication connection（Printer（DP-1VA））
The measured values can be printed out by Mitutoyo's Digimatic Mini Processor (DP-1VA).

Digital Torque Meter
Dedicated cable* The cable is available as an option.

SET_SAVECANCELVALUE_READ* An example of send command input
Set the comparator HI to 10.0.
Command: setting value CR + LF
COMP_HI: 10.0 CR+LF* Receive a reply message of "COM_OK!!", if the command input is correct.
* Receive a reply message of "COM_ERR!!", if the command input is incorrect.
* Be sure to send "SET_SAVE" after changing the settings. Otherwise,the settings will not be enabled and the display
will not return to the measurement screen, either.
* Once set, it cannot be returned to the original value.
