or impacts.

Please read the following safety precautions
to ensure safe and correct operation.

• Always detach the bit from the sensor unit afteruse.

■ Before using• Before you begin using the instrument, read theoperating instructions and also the precautions
given on the seal affixed to the instrument.
• The torque meter's display unit and sensor unit
come with the same serial number. These twoparts of the instrument are calibrated together;
do not use any different combination.
• HIOS cannot assume responsibility for accidents or difficulties when the instrument has
been remodeled or disassembled, or when it has
been used in a way other than that explained in
the operating instructions.

• Use of the battery charger
See page 9 for instructions on battery charging.
• Use only the products specified in these operating instructions for connection to the data output ports.
• When disconnecting cables, grasp the cable plugand take care not to damage connector pins.
• Always turn the power switch off after completing measurement operations.
• Do not strike the acrylic display panel or place
heavy objects on it.
• Avoid excessive internal adjustments for calibrating or other purposes.
• Handle the instrument with care and take care
not to drop it.

■ During operation• Be sure to attach the bit securely into the sensor
unit chuck.
• For safety, make sure the bit never points atanything other than the tool to be measured.

• This instrument is sensitive to ambient conditions. Avoid using it in the following kinds ofplaces:• Places where water, oil or other liquids could

fall onto or get inside the instrument.

■ Operating instructionsFirst check the state of the battery charge. Whenthe power is on and the battery has an insufficientcharge, the display reads "LOBAT." When this happens, use the battery charger to recharge the battery
for at least 3 hours and no more than 6 hours.
1. Connect the sensor and display units using thesensor unit cord. The plugs on either end of thiscord have the same pin arrangement, so it doesn’t
matter which unit gets which plug, but one is Lshaped and the other is straight, so choose the
combination most convenient for operation.
When making the connection, look at the pins in
the plug and take care to fit them smoothly into
the connector to avoid bending them.
2. Attach the bit provided with the torque meter tothe sensor unit.

8. To output data using a Mitutoyo Input Tool, set
the No. 3 connector of the DIP switch (page 7)
to the on position (so the "P.ON" LED lights),
set the【MODE】switch to "PEAK" and press
the【RESET】switch (which functions the sameas the Enter key on a computer) . The Input Tool
will convert the measurement data for direct
input to a spreadsheet application. In order to
output data, please conduct measurement within
the instrument's peak measurement range, as indicated in the specifications.
• Minus signs denoting counterclockwise torqueare transferred with the measurement data.
9. Fit the bit into a fastened screw to be tested.
Clockwise rotation measures tightening torqueand counterclockwise rotation measures loosening torque. All torque measurements are displayed digitally and the data is stored.
10.Be sure to turn off the power when you are finishedmeasuring.

Fit the joint shaft collar overthe driver and insert the bit
into the collar.

3. Select the unit of measurement desired【UNIT】switch. (N•m↔N•cm) (N•m↔lbf•in)(N•m↔kgf•cm)
4. Conduct zero adjustment. Set【MODE】switch
to "TRACK," then press both the【SET】and【▲】switches at the same time for less than 2seconds. This adjusts the meter to zero. (Note:
If you press the switches for than 2 seconds, themeter will go into another mode. If this happens,press【RESET】, then repeat the zero adjustment process.)
5. Set【MODE】switch to "PEAK" or "F.PEAK."• In peak mode the peak torque value reached during measurement is displayed. Thus, the display
does not change. Model HDP-50 measures up to
10 N•m of torque, which corresponds to a display value of 15. Please conduct measurements
within this range.
• In "F.PEAK" mode the first peak value is displayed and does not change even if higher torqueis applied.
6. Press the【RESET】switch to cancel the display.
7. Minus signs appear in front of measurements ofcounterclockwise torque.
