READ FIRST: SAFETY INFORMATION
For safety, and for damage avoidance, be sure to read this manual thoroughly. The warranty is only valid when the
product is used following the instructions provided within this manual.
• Do not use tester in high temperature, high humidity, or in a damp or wet place.
• Recommended operating temperature is 0 - 42°C (32 - 100°F).
• Do not apply torque exceeding the rated capacity, regardless of whether the unit is on or off. Avoid shock load.
Do not use with impact wrenches. Note: the driver adapter capacity is less than the unit capacity.
• To charge the battery only use the AC adapter/charger provided.
• Securely fasten the unit to a stable work surface by tightening the mounting screws to avoid spinning and
possible accidents.
• Do not use lacquer thinner or any solvent to clean the unit.
• Do not disassemble or modify the unit.
• When not in use, store tester in carrying case provided.
1. POWER SWITCH Press to turn on, press again to turn off (click once, do not
hold). After 10 minutes of non-use, unit shuts off.
2. MODE Select Real Time, PP (Peak), PD (Peak Down) or C (Continuous
Output Mode).
3. CLEAR Reset display to zero and send data to memory.
4. LCD display Displays torque value, battery icon, mode and units.

GENERAL OPERATION (for Power Drivers)
1. Select an appropriate driver adapter, place it on the measuring head and
secure by tightening all four holding screws (M3) included. Use a test screw
). Screw it all
to match the power driver tip (i.e. flat head, Phillips,
the way into the driver adapter.
2. To select the desired measuring unit (in-lb, kg-cm, N-m, N-cm), press
Power then hold UNITS for 4 four seconds until a beep sounds. Press
UNITS to cycle choices. Press PRG/SET to enter.
3. Press and hold MODE for one second to select from the following
measuring modes:
Real Time – Displays torque transients (no output or indicator)
PP Mode – Peak, captures peak torque (peak data output, PP appears on
display)
PD Mode – First Peak, capture first peak value (peak data output, PD
appears on display.
C Mode – Continuous RS-232 output display and output torque transients
(180 data/sec., GOOD indicator flashes).
4. Press CLEAR to reset the display to “0”
5. Before measuring, always make sure that the unit is mounted securely to a
stable work surface (retighten the mounting screws if necessary).
Back out screw for spring adapters
6. Back out the screw in the spring adapter prior to testing. There is no need to
do this for Smart adapters as they release torquing energy automatically.
Insert driver tip into the adapter securely and perpendicularly (not at angle).
Turn on power driver and tester will measure and display torque value.
7. After taking measurement, press CLEAR for the next test.

PROGRAMMING
Press POWER to turn on. Press PRG/SET for one second. The display shows “HI” and then the High setpoint
value. This confirms the tester is ready for the following program steps.
1. High Setpoint (HI) After “HI” is displayed and the High setpoint value, press SHIFT (8)
to move the numeric place (selected place flashes) and press UP (9) to select values i.e.
50.0 for 50.0 lbf-in, then press PRG/SET (10) to enter.
2. Low Setpoint (LO) After High value is entered, “LO” is displayed, then the Low
setpoint value. Press SHIFT to move the numeric place and press the UP to select
values, then press PRG/SET to enter.
3. Peak Down Minimum (PdLO) After Low value is entered, “PdLO” is displayed, then
the PdLO value. Press SHIFT to move the numeric place and press the UP to select
values, then press PRG/SET to enter.
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.
4. Continuous Data Output Minimum (CLO) After Peak Down value is entered, “CLO” is displayed, then the CLO
value. Press SHIFT to move the numeric place and press the UP to select values, then press PRG/SET to enter.
CLO sets the start and stop trigger points for Continuous data output. When torque reaches the CLO value, the
tester starts to output data and stops if torque falls below the value. Note: the display does not show any value
below the CLO minimum.
5. Auto Zero Reset (AC) After Continuous Data Output Minimum is entered, “AC” is displayed, then the Auto Zero
Reset duration value. Press UP or DOWN/SHIFT to select 0.0C – 0.1C – 0.5C – 1.0C – 1.5C – 2.0C – 2.5C – 3.0C,
and press PRG/SET to enter (0.1C for 0.1 second and 0.0C for MANUAL RESET).
After measuring, Auto Zero automatically resets the tester to “0.0”
6. Beeper (bp) After Auto Zero Reset is entered, “bp” is displayed, then “On”. Press UP or DOWN/SHIFT to select
On, OFF or FF, then press PRG/SET to enter.
After “bp” is entered, “-S-“ is displayed to confirm programming completion and zero is shown.
After High and Low setpoints are set and beeper is set to On,
In PP mode
Under LO setpoint – no LED light or beep
Over LO setpoint - Green LED lights and beep sounds
Over HI setpoint – NG flashes and beep sounds
In PD mode – no indicator or beep for values before Peak Down is sensed.
Under LO setpoint – NG flashes and slow beep sounds
Between LO and HI – GOOD lights and constant tone sounds
Over HI setpoint – NG flashes and fast beep sounds
In Real Time mode
Under LO setpoint – no LED light or beep
Between LO and HI – GOOD lights and beep sounds
Over HI setpoint – NG lights solid and beep sounds
DATA MEMORY
Storing and Recalling Data from Memory
Memory functions work in PP and PD modes. Store up to 800 values in memory.
1. Measure in PP or PD mode, when the display resets either Auto Zero or manually pressing CLEAR, the
peak value is stored.
2. To recall a value, press MEMORY and the last stored memory is displayed. Press UP or DOWN/SHIFT to
select a memory location (i.e, .0.01 for first location) and torque value. The display cycles between memory
location and value.

press CLEAR, “CLR” is displayed. Press CLEAR again to clear the data and “- - - -“ is displayed to confirm
deletion.
All clear: Press CLEAR and hold until the display shows “ALL” then press CLEAR again and “- - - -“ is
displayed to confirm deletion.
Downloading Memory Data
1. Press ON/OFF to turn on
2. Press MEMORY and after memory data is displayed, press MEMORY again and “FA” is displayed. Use UP
or DOWN/SHIFT to select the first memory location then press MEMORY and “LA” is displayed. Use UP or
DOWN/SHIFT to select the last memory location. Press MEMORY again and the data is sent. While data is
output -P- is displayed.
Statistics
Press STATISTICS and the number of data, Max, Min and Avg are displayed in sequence.
Auto Power Off
To maximize the life of the battery, power automatically shuts off after 10 minutes of non-use.
Low Battery Indicator
Battery Indicator status shows full, half or needs recharging. If the battery is empty, power is
turned off immediately. IMPORTANT! Use the provided AC charger/adapter exclusively and
plug into correct AC outlet. It takes 3 hours to fully recharge for 12 hours of continuous use.
When fully charged, the charge light goes off.
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.
USB OUTPUT
RS-232 Virtual COM Port
When the tester is connected to a computer’s USB port and turned on, Windows XP or Vista will recognize the
tester and ask to connect to the Internet. Allow Windows Update to connect to the Internet and follow the
instructions on your screen to download and install two drivers for the RS-232 virtual COM port. For Windows, 98,
ME and MAC, go to www.ftdichip.com/Drivers/VCP.htm.
The PC and tester will communicate through the USB port the same as a COM port. To verify the COM port
number open the Device Manager, select the + sign next to the Ports icon and note the COM port number.
