■ Introduction
HIT Digital Torque Meters directly measure torque of impact drivers, pneumatic drivers, clutch-type
torque wrenches, etc. Its rst peak circuit gives high accuracy of torque of impact drivers. Battery
powered and easily brought to the assembly line or work place, you will nd it extremely handy to use.
It can be connected to a printer for greater usefulness in quality control. A must for safety control of
bolts and nuts.
■Features
●Rechargeable instrument for measuring the torque of impact drivers, pneumatic drivers and torque
wrenches.
● Audible signal can be set to sound at desired torque level in peak and rst peak modes.
●The only instrument you need for measuring N•m, kgf•cm and lbf•in.
●Digital display eliminates readout errors.
●Measures in either direction.
●Has printer and analog output terminals.
●Compact, light and rechargeable, for ease of portability.

●Printer output connector
The meter performs recording of data, structuring them into statistics, compute processing and
also can be connected to personal computers, thus can be developed to high quality information
processing system. This system is called SPC (Statistical Process Control).
●Unit converter switch
lbf•in ←→ kgf•cm ←→ N•m
●Mode switch
PEAK Holds load value (clear with reset button).
TRACK Display changes according to load (cleared by removing load).
FIRST PEAK Measures rst peak and gives an audible signal when rst peak is reached (Requires
a differential of at least 5.0 kgf.cm).
●Socket
This socket is for attaching the device to be measured.
 ● Buzz set
The buzz set function informs users of arrival at a desired torque with a buzz.

■Operation
First check the battery level!
Turn the power switch on. If the charge is inadequate, the message "LOBAT" will be displayed. In that
case, recharge the battery for about 3 hours. Never recharge for more than 8 hours.
1. Bolt the detector unit to the work bench.
2. Set unit converter switch to the desired measurement unit.
3. Set mode switch to the desired measurement mode and use
the zero adjusting knob to adjust the displayed value to zero.
4. Conducting measurement
•Track measurement:
Set mode switch to "Track." Changing torque values will
be displayed according to the load to the detector unit.
Display returns to zero when the load is removed.
•Peak measurement:
When peak measurement is desired, set the Mode
Switch at PEAK. The peak value is held for more than 5
seconds when more than 15 digits signals are inputted.
It can be cancelled by pushing the reset button.
•First peak measurement:
Set mode switch "First peak." Use for measuring torque wrenches. Measures rst peak values
and gives an audible signal when rst peak is reached.
* Use size 9.5 x 9.5 or 12.7 x 12.7 square sockets (commercially available), or make a socket
adaptor for other sizes.
Measurement of impact drivers
(1) Attach a 9.5 x 9.5 or 12.7 x 12.7 square socket adapter to the detector unit socket.
(2) Fit the driver into the adaptor and start the motor.
(3) The peak load value will be displayed. Read off this value and push the reset button to cancel
the value.
(4) Repeat the above process as necessary.
Torque wrench measurement
(1) Set mode switch to "FP."
(2) Attach a 9.5 x 9.5 or 12.7 x 12.7 square socket adapter to the detector unit socket.
(3) Fit the wrench into the adaptor and start the motor.
(4) You will hear a "click" when the rst peak has been measured. The display freezes on this
value. It does not change with changing load to the detector unit.
(5) Read off this value, then push the reset button to cancel it.
(6) Repeat the above process as necessary.

5. When using a printer set the mode switch to "Peak." When peak measurement is desired, set the
Mode Switch at PEAK. The peak value is held for more than 5 seconds when more than 15 digits
signals are inputted. It can be cancelled by pushing the reset button. (There are reset buttons on
the display and the detector unit.)
6. See "Setting torque level signal tone" below to set the signal tone to sound when the desired
torque level is reached.
7. When you are nished measuring, turn off the power switch and remove the driver, etc. from the
socket.
 ■ How to set the buzz set
1. Turn the zero adjustment knob until the desired torque value is displayed.
2. Turning the buzz set volume control to the left causes the signal to sound, then stop turning.
3. Turn the zero adjustment knob until the displayed value reads zero. (Note that the set value is not
displayed, so it may be helpful to make a written note of it.)
4. If the mode switch is set to track mode, the buzz will sound at the preset value. This can be turned
off by removing the load to return the display to zero.
5. In peak measurement, when the preset load is reached, the buzz will stop and the value will freeze
on the peak value. The display can be returned to zero by pressing the reset button.
6. To terminate the buzz set, turn the volume control all the way to the right. When not using the
signal tone, keep the volume control set turned all the way to the right.

Recharging
Turn the power switch off before recharging, using the recharging unit. A full recharge takes less than
8 hours.
(Caution)
•Never recharge for more than 8 hours.
•Do not use the recharging unit for recharging anything but HIT Digital Torque Meters.
•Do not use the instrument during recharging.
■
Type of data output
Use the Mitutoyo Input Tool (available for purchase from many dealers) to transfer measurement data
to a computer.
• Measured data input unit input tool (USB keyboard conversion type)
Model: No. IT-016U
* Uses Mitsutoyo Connection cable, No. 06AGF590 2 m (sold separately)

 ■ Analog output
This instrument can be connected to Pen recorders, Vidi-light recorder, Oscilloscopes, Voltmeters, etc.
When using with these products, please refer to the appropriate operation manuals.
 ■ Inspection and calibration
The detecting element of the HIOS Digital Torque Meter has a specially designed structure and
maintains its stabilized load accuracy over a long period of time. However at least once a year
inspections are required to get the best use from the Meter. Calibration can be practiced by customers
using a weight and weight hanging disk (optionally available) to be attached to the Joint Shaft while the
Detector is horizontally held by a clamp. When a stabilized and correct state cannot be achieved by
the customer, adjustment and repair will be carried out by local authorized distributors. When the jam
is found exceeding local technical ability, the Meter will be repaired by the manufacturer.
 ■ Attention
The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the
end of it’s useful life, under various state and local laws, it may be illegal to dispose of this battery into
the municipal waste stream.
Check with your local solid waste officials for details in your area for recycling options or proper
disposal.
 ■Caution
• Never apply more torque than the tolerance level given in the specications, as this could damage
the instrument.
•Do not strike the plastic display panel or place heavy objects on it.
• Because torque meters are sensitive to ambient conditions, it is necessary to occasionally perform
zero adjustment.
• Take care to shield the instrument from exposure to water, oil or other liquids, vibration, dust,
hot air, indoor or outdoor electrical noise, high humidity (operating humidity range is 35-65%),
temperature extremes (operating temperature range is 15℃ - 40℃) and all other conditions that
could harm the instrument or impair its functioning.
•Do not remove the back panel for calibration, etc.
•Refrain from rough usage or dropping of the instrument.
• Do not store in places subject to high humidity or extreme drops in humidity that could result in
harmful condensation inside the instrument.
•Please note that the display and detector units of your HIT Digital Torque Meter each have the
same serial number because they are calibrated together and are meant to be used together.
