Measurement of average torque
Objective
Use for routine checks of loosening and tightening
torque.
Measurement procedure
Makes possible measurement of the minimum,
average and maximum values among sets of mea-
surements, each set consisting of up to ten measure-
ments.
1. The measurement results are automatically num-
bered, from 0001 to 0010. Negative displays are
not recorded. Measurements in average mode are
automatically deleted when the meter exits aver-
age mode.
2. If less than 10 measurements are made, the dis-
play shows only those measurements.

Battery charger
To charge batteries for the HIOS torque meter use
only the battery charger provided with the meter.
Always turn the power off when charging. The rst
time will require 6 hours for a full charge.
Caution
•
Do not recharge the battery for longer than 6
hours.
•
Use only NiMH batteries, never any other kind,
even if obtained from HIOS Corporation.
•
Do not use the meter while charging the battery.
•
When the letters "LOBAT" appear in the display,
stop measurement and recharge the battery.
•
Do not use the battery charger for any purpose
other than charging batteries for this instrument.
•
Do not place objects on top of the battery char-
ger's cord. Do not subject the cord to extreme
bending or tie it in knots.
•
Be sure the power to the instrument is off when
attaching or detaching the battery charger.
•
Do not attempt to remove the battery from the
instrument.
Danger!
•
Leaving the battery charger on for the maximum
recharge time of 6 hours could lead to overheat-
ing, damage to the instrument or res.
■
How to recharge
1. Turn off the power to the torque meter and insert
the battery charger cord into a power source.
2. When recharging is complete, unplug the cord,
turn the torque meter power switch on and check
that the display goes on.
3. Wait for the battery charger to cool, and store it
in an appropriate location.
