Operating Procedure; Operating Instructions - HIOS HDP-50 Operation Manual

■ Operating instructions

First check the state of the battery charge. When
the power is on and the battery has an insufficient
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 fit them smoothly into
the connector to avoid bending them.
2. Attach the bit provided with the torque meter to
the sensor unit.
3. Select the unit of measurement desired
【 UNIT 】 switch. (N

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

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 specifications.
• 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 finished
measuring.
