General Operation

1. 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 the display)
PD Mode – First Peak, capture first peak value (peak data output, PD appears on the display)
C Mode – Continuous RS-232 output, Display and output torque transients (12 or 180 d ata/sec., C appears

on the display.

2. Place the appropriate size socket onto the drive, and if desired, the one-way clutch also.

3. Rotate the wrench head so the display may be viewed while measuring.

4. Press the CLEAR button on the display unit to zero the display. Insert the socket onto the bolthead, hold
perpendicularly (not at an angle) and turn to measure.

Programming

Click ON/OFF to turn on. Press PRG 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 to move the
numeric place and press UP to select values, then press PRG to enter.

2. Low Setpoint (LO)

After high value is entered, LO is displayed, then the low setpoint value. Press
DOWN to move the numeric place and press UP to select values, then press
PRG to enter.

3. Peak Down Minimum (PdLO)

After low value is entered, PdLO is displayed, then the PdLO value. Press down
to move the numeric value and press up to select values, and press PRG 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 that will be measured in Peak Down mode.

4. Continuous Data Output Minimum

After Peak Down value is entered, CLO is displayed, then the CLO value. . Press DOWN to move the numeric
place and press UP to select values, then press PRG to enter.

5. Auto Zero Reset (AC)

After Continuous Data Output Minimum is entered, AC is displayed and then the Auto Zero Reset duration
value. Press Up or Down to select 0.0C-0.1C-0.5C-1.0C-1.5C-2.0C-2.5C-3.0C, and press PRG to enter (0.1C
for 0.1 second and 0.0C for Manual Reset)

6. Batch Counter (CO)

After the Zero Value is entered, CO is displayed then the CO value. Use the UP or DOWN keys to select a
value and PRG to enter (0-99, clockwise only)

7. Interval (In)

After the Batch Counter value is entered, In is displayed then the In value. the UP or DOWN keys to select a
value and PRG to enter (0-24 in 22-second increments)
