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 (180 data/sec., C appears on
the display)

2. Insert Phillips tip into the screwdriver.

3. To select ratchet operation turn the ratchet one
click clockwise or counter-clockwise from the
center position. To disable ratcheting, turn it so
the semi circle is in the center position.

4. Press the CLEAR button on the display unit to
zero the display. Insert the screwdriver tip into
the screw, hold perpendicularly (not at an
angle), and turn to measure.

5. After measuring, press CLEAR to zero the display for the next test.

PROGRAMMING

Press POWER 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 i.e. 50.0
for 50.0 lbf-in, 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 the UP to
select values, then press PRG to enter.

TORQUE MEASUREMENT

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.

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 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 USB virtual com port. For Windows 98, ME and
MAC go to www.ftdichip.com/Drivers/VCP.htm.

3. Peak Down Minimum (PdLO)

After Low value is entered, "PdLO" is displayed, then the PdLO
value. Press DOWN to move the numeric place and press the UP
to select values, then 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

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 to move the numeric place and press
the UP to select values, then press PRG 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 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).

After measuring, Auto Zero automatically resets the tester to "0.0".

6. Batch Counter (CO)

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

7. Interval (In)

After the Batch Counter value is enetered, "In" is displayed, then
the In value. Use the UP or DOWN keys to select a value and
press PRG to enter (0-24 seconds in 2 second increments).

8. Beeper (bp)

After Interval value is entered, "bp" is displayed, then "On". Press
UP or DOWN to select On, OFF, or FF, then press PRG to enter.
"On"– beeper sounds for Good, NG and capacity overload
"OFF"– beeper sounds for capacity overload only
"FF"– beeper sounds for NG and capacity overload.

9. Units (Un)

After the Beeper is programmed, "Un" is displayed, then the current
unit selection. Press UP to cycle the units; lbf-in, ozf-in, kgf-cm,
N-m and N-cm.

After Units are 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– Green LED lights
Over HI– Red LED flashes and beep sounds

In PD mode– no indicator or beep for values before Peak
down is sensed.

Under LO setpoint– Red LED flashes and slow beep sounds
Between LO and HI– Green LED lights and constant tone sounds
Over HI– Red LED flashes and fast beep sounds

In Real Time and C mode

Under LO setpoint– no LED light or beep
Between LO and HI– Green LED lights and beep sounds
Over HI– Red LED lights 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 by either
Auto Zero or manually pressing CLR, the peak value is stored.

2. To recall a value, press MEM and the last stored memory is dis­played. Press UP or DOWN to select a memory location (i.e.
.0.0.1 for first location) and torque value. The display cycles
between memory location and value.

Clearing Data from Memory

Single clear: Press MEM, then press UP or DOWN to move to a

memory location. When the desired memory value is displayed,
press CLR, "CLR" is displayed. Press CLR again to clear the data and
"– – – –" is displayed to confirm deletion.
All clear: Press CLR and hold until the display shows "ALL" then
press CLR again and "– – – –" is displayed to confirm deletion.

Downloading Memory Data

1. Press ON/OFF to turn on.

2. Press MEM and after memory data is displayed press MEM again
and "FA" is displayed. Use UP or DOWN to select the first memo­ry location then press MEM and "LA" is displayed. Use UP or
DOWN to select the last memory location. Press MEM again and
data is sent. While data is output -P- is displayed.

Note: By pressing DOWN switch for more than 1 sec, the download
function can be terminated.

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 CEDAR AC adapter/charger
exclusively and plug into the correct AC output. It takes 5 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.
