Safety Precautions
■Before using
•Before you begin using the instrument, read the
operating instructions and also the precautions
given on the seal afxed to the instrument.
•The torque meter's display unit and sensor unit
come with the same serial number. These two
parts of the instrument are calibrated together;
do not use any different combination.
•HIOS cannot assume responsibility for ac-
cidents or difculties 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.
■During operation
•Be sure to attach the bit securely into the sensor
unit chuck.
•For safety, make sure the bit never points at
anything other than the tool to be measured.
•When using the support arm that comes with
Model HDP-50, be sure to attach it securely to
prevent it from coming loose under high torque
loads.
•To avoid damaging the sensor unit, do not sub-
ject it to rough handling.
•If the torque meter shows any functioning ab-
normality, cease operation immediately and
contact HIOS Corporation or your HIOS dealer.
•Operators of power tools should always button
cuffs and shirt fronts and fasten zippers on ap-
parel when conducting operations.
•Operators of power tools should not wear gloves,
as this interferes dangerously with having a
proper grip on the tools.
■Precautions in operating a digital
torque meter
•Never exceed the maximum torque levels indi-
cated in the specications on page 10. Exceed-
ing capacity load levels by 120% will result in
internal damage to the meter.
•The battery charger is for NiMH batteries only. Nev-
er use any other kind of battery, even from HIOS.
•Do not disassemble the instrument or loosen the
screws on its body, as this could cause inaccu-
racy in measurement.
•Protect the display and sensor units from shocks
or impacts.
•Always detach the bit from the sensor unit after
use.
•Use of the battery charger
See page 8 for instructions on battery charging.
• Use only the products specied in these operat-
ing instructions for connection to the data out-
put ports.
•When disconnecting cables, grasp the cable plug
and take care not to damage connector pins.
•Always turn the power switch off after complet-
ing measurement operations.
•Do not strike the acrylic display panel or place
heavy objects on it.
•Avoid excessive internal adjustments for calibrat-
ing or other purposes.
•Handle the instrument with care and take care
not to drop it.
•This instrument is sensitive to ambient condi-
tions. Avoid using it in the following kinds of
places:
•Places where water, oil or other liquids could
fall onto or get inside the instrument.
•Places subject to vibration, dust or hot air.
•Outdoors, or places where electrical discharges
may occur.
•Places of high temperature or humidity. (Operat-
ing humidity and temperature ranges for digital
torque meters are 25% − 65% and 15℃ − 35℃).
•Any other place where there is a danger of the
instrument being damaged or its functioning
impaired.
•Please do not store the instrument in places of
high temperature or high humidity. This could
result in condensation forming inside, which
could endanger functioning.
Please read the following safety precautions
to ensure safe and correct operation.

8. To output data using a Mitutoyo Input Tool, set
the No. 3 connector of the DIP switch (page 6)
to the on position (so the "P.ON" LED lights),
set the【MODE】switch to "PEAK" and press
the【RESET】switch (which functions the same
as 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 in-
dicated in the specications.
•Minus signs denoting counterclockwise torque
are transferred with the measurement data.
9. Fit the bit into a fastened screw to be tested.
Clockwise rotation measures tightening torque
and counterclockwise rotation measures loosen-
ing torque. All torque measurements are dis-
played digitally and the data is stored.
10. Be sure to turn off the power when you are nished
measuring.
■Operating instructions
First check the state of the battery charge. When
the power is on and the battery has an insufcient
charge, the display reads "LOBAT." When this hap-
pens, 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 the
sensor unit cord. The plugs on either end of this
cord have the same pin arrangement, so it doesn’t
matter which unit gets which plug, but one is L-
shaped 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 t them smoothly into
the connector to avoid bending them.
2. Attach the bit provided with the torque meter to
the sensor unit.
Fit the joint shaft collar over
the 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 2
seconds. This adjusts the meter to zero. (Note:
If you press the switches for than 2 seconds, the
meter will go into another mode. If this happens,
press【RESET】, then repeat the zero adjust-
ment process.)
5. Set【MODE】switch to "PEAK" or "F.PEAK."
• In peak mode the peak torque value reached dur-
ing measurement is displayed. Thus, the display
does not change. Model HDP-50 measures up to
10 N•m of torque, which corresponds to a dis-
play value of 15. Please conduct measurements
within this range.
• In "F.PEAK" mode the first peak value is dis-
played and does not change even if higher torque
is applied.
6. Press the
【RESET】switch to cancel the display.
7. Minus signs appear in front of measurements of
counterclockwise torque.

•Shipping and handling charges incurred for re-
pair service must be paid by the customer. Please
direct questions about customer services to HIOS
Corporation or your HIOS dealer.
■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 bat-
tery into the municipal waste stream. Check with
your local solid waste ofcials for details in your
area for recycling options or proper disposal.
■Inspections and calibration
HIOS torque meters employ a unique sensor mech-
anism that maintains accuracy for long periods. We
recommend that the torque meter be sent in to HIOS
Corporation for inspection at least once a year. (Note
that a fee is charged for this service.)
HIOS torque meters are shipped calibrated to meet
our accuracy standards. Depending on the condi-
tions under which the meter is used, accuracy may
be affected over the course of months or years.
Therefore, HIOS offers calibration and, when nec-
essary, overhaul services. We also recommend use
of the periodic calibration documentation included
with the torque meter. This documentation shows
the relation of the HIOS standards to Japan's stan-
dards.
■Cautions to be observed when
sending the torque meter in for
calibration or repair
1. Pack the meter in the attache case in which it
was originally shipped to protect it from violent
impacts during shipping.
2. Do not put anything into the attache case other
than the items originally shipped inside. Never
include items such as homemade mounting
plates, tools or extra bits. HIOS cannot assume
responsibility for these.
3. Please explain the nature of the difculty with
the instrument in sufcient detail.
