TORQUE MEASUREMENT
OUTPUT
USB 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 con-
nect 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 USB 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.
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 programming steps.
1.
High Setpoint (HI)
After "HI" is displayed and the High setpoint
value, press DOWN/SHIFT
to move the
numeric place (selected place flashes) and
press UP
to select values i.e. 50.0 for 50.0
lbf-in, then press PRG/SET
to enter.
2.
Low Setpoint (LO)
After High value is entered, "LO" is dis-
played, then the Low setpoint value. Press
DOWN/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 DOWN/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 DOWN/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 dis-
played, 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".
