SELECTING RATCHET OPERATION
1. To disable ratcheting, turn the ratchet so the
semi circle is in the center position.
2. Enable CW ratcheting operation by turning the
ratchet one click counter-clockwise from the
center position.
3. Enable CCW ratcheting operation by turning
the ratchet one click clockwise from the cen-
ter position.
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, then the High setpoint value.
The tester is now ready for the following programming 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. 25.0 for
25.0 lbf-in (for lbf-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.
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 setpoints and batch counter are set, the tester counts the num-
ber of properly torqued fasteners (between High and Low setpoint)
and beeps three times when completed. If time ("In" value) elapses
before reaching the batch count number, a beep sounds to alert to
possible mis-tightening or stripped thread.
