IMPORTANT!Use the provided AC adapter/charger exclu-
sively and plug into the correct AC output. It takes 8 hours to fully
recharge. Do not recharge for more than 12 hours. When fully
charged, disconnect the AC adapter/charger to avoid overcharging.
In order to avoid high heat, explosion or toxic fumes, please note
the following precautions:
1. Be sure to use only the provided AC charger exclusively.
2. Do not plug the charger into unspecified higher voltage.
3. Do not recharge until LOBAT icon appears.
System Reset
When battery power is completely depleted, the tester may not
work even though it has been recharged. In this case, press the
System Reset Button.

Consistent readings no matter where the wrench is gripped because
the torque sensor is centered on the drive.
Storing and Recalling Data from Memory
Memory functions work in PP, PD and C modes. Store up to 300
values in memory.Values are simultaneously output as RS-232
even after memory is full.
1. Measure in PP or PD mode, press CLR/PRG to store peak values.
In C mode, the tester outputs data continuously (80 data/sec).
2. To recall a value, press UP or DOWN to select a memory loca-
tion, the display cycles between location and torque value (i.e.
.0.0.1 for first location).
Note: Selecting an invalid location, defaults to measurement mode.
Clearing Data from Memory
1. Single Clear: When a memory value is displayed, press CLR/PRG,
then “CLR” displays and blinks 3 times. Press CLR/PRG switch
again before “CLR” stops blinking and the memory value is erased.
2. All Clear: Press CLR/PRG and DOWN simultaneously until “ALL”
is displayed.While “ALL” is blinking, press CLR/PRG again. Display
changes to “CLR” and blinks 3 times. Press CLR/PRG again before
“CLR” stops blinking and all memory data is erased.
Downloading Memory Data
1. Press ON/OFF to turn on.
2. Press UP and DOWN switches simultaneously. The display blinks
"FA" twice and then displays numbers with decimal points in
between (.0.0.1 for first memory location).
3. Press UP or DOWN switch to select the desired beginning mem-
ory location and press CLR/PRG to enter. The displays blinks
"LA" for the ending memory location.
4. Press UP switch or DOWN switch to select the desired ending
memory location and press CLR/PRG to enter.
5. Press CLR/PRG switch to download the data.While downloading
the data, the display shows "-P-".
Note: By pressing DOWN switch for more than 1 sec, the download
function can be terminated.
Auto Power Off
To maximize the life of the battery, power automatically shuts off
after 10 minutes of non-use.

GENERAL OPERATION
1. Place the appropriate size socket onto the drive.
2. Rotate the wrench head so the display may be viewed while
measuring and position the socket securely over the bolt (not at
an angle) and turn to measure.
3. After taking measurement, press CLR/PRG switch to zero display
for the next test.
SELECTING MEASURING MODES
Press ON/OFF to turn on. Hold CLR/PRG for more than 4 seconds.
Display cycles GO, PP, PD or C. Select desired measuring mode,
which becomes the default mode. Press CLR/PRG to display the mea-
suring mode.
GO (Real Time) Display torque transient (no output).
PP (Peak) Capture peak torque (peak data output).
PD (Peak Down) Capture peak down value (peak data output).
C(continuous RS-232 output, 80 data/sec) Display torque tran-
sients.
PROGRAMMING (to exit programming at any time press OFF)
Press ON/OFF to turn on. Press CLR/PRG and UP switches simulta-
neously and hold for more than 4 seconds.The Green LED lights
and one beep sounds, "HI" is displayed and then the High setpoint
value. This confirms the tester is ready for the following program-
ming steps.
1. High Setpoint (HI)
After "HI" is displayed and then the High setpoint value. Press UP
or DOWN switch to select the High setpoint value i.e. 50.0 for
50.0 lbf-in (for lb-in gauge), then press CLR/PRG to enter.
2. Low Setpoint (LO)
After High value is entered, "LO" is displayed and then the Low
setpoint value. Press UP or DOWN switch to select the Low set-
point value, then press CLR/PRG to enter.
3. Peak Down Minimum and Trigger Point (PdLO)
After Low value is entered, "PdLO" is displayed and then the PdLO
value. Press UP or DOWN switch to select, then press SET to enter.

TORQUE MEASUREMENTTORQUE MEASUREMENT
PdLO sets a minimum torque value for Peak Down mode. For
example, if "PdLO" value is set at 5.0 lbf-in, only a reading over
5.0 lbf-in will be measured in Peak Down mode.
PdLO also sets the start and stop trigger points for Continuous
data output.When torque reaches the PdLO value, the gauge
starts to output data and stops if torque falls below the value.
4. Batch Counter (CO)
After "PdLO" value is entered, "CO" is displayed and then the
batch count number. Press UP or DOWN switch to select (0 to
99), then press CLR/PRG to enter.
Batch counter retains the number of properly torqued fasten-
ers counted in memory even if the tester is turned OFF. Press
and hold ON/OFF for more than 1 second to reset.
5. Beeper (bp)
After the batch count number is entered, "bp" is displayed and the
display shows "On" for beeper set ON, "Off" for beeper set OFF or
"FF" for no beep unless over high setpoint. Press UP or DOWN
switch to select, then press CLR/PRG to enter.
6. Auto Zero Reset (AC)
After Beeper selection is entered, "AC" is displayed and then Auto
Zero Reset duration value. Press UP or DOWN to select 0.0C -
0.5C - 1.0C - 1.5C - 2.0C - 2.5C - 3.0C, and press CLR/PRG to
enter (0.5C for 0.5 second and 0.0C for MANUAL RESET).
After measuring, Auto Zero automatically resets the tester to "0.0".
7. Time (In)
After Auto Zero Reset is entered "In" is displayed and then the
Time duration.Press UP or DOWN switch to select (0 to 24 sec-
onds), then press CLR/PRG to enter.
After "In" is entered, "S-" is displayed to confirm programming com-
pletion and 0.0 is shown.
After High and Low setpoints and batch counter are set, the tester
counts the number of correctly torqued fasteners (between High
and Low setpoint). When completed, tester flashes the Green LED
and beeps three times. If the "Time" duration ("In" value) elapses
before reaching the batch count number, the Red LED flashes and
beep sounds to alert to possible mis-tightening or stripped thread.
