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.
l
Do not use tester in high temperature, high humidity, or in
damp or wet areas.
l
Recommended operating temperature is between 0-42ºC (32100ºF).
l
Do not apply torque exceeding the rated capacity, regardless of
whether the unit is On or Off.
l
When charging the battery, be sure to use the provided AC
adapter/charger exclusively.
l
When measuring torque, the unit will have a tendency to turn. In
order to avoid spinning and possible accident, it is very important to securely mount the unit to a stable work bench.

GENERAL OPERATION
IMPORTANT! Always make sure that the sensor is mounted securely
to a stable workbench to avoid spinning and possible accident.
1. Connect the torque sensor to the tester display unit with cable
provided. When connecting the cable to the torque sensor,
rotate the round connector to find the matching groove, then
push in until it makes positive connection (When disconnecting
the cable, hold the silver metal part of the round connector and
pull out).
2. Select measuring unit (lbf-in/lbf-ft, kgf-cm/ kgf-m, or N-cm/N-m).
If desired, affix unit designator to prevent it from being accidentally changed.
3. Select among the following
Measurement Modes (For normal testing, PP mode is recommended).
PP (Peak Mode): Capture peak torque
PEAK Torque reading will not change
until a higher value is measured (peak
data output).
C (Real Time Mode): Display torque transient (no output).
PD (Peak Down Mode): Capture first peak value and will not
change even if a higher value is subsequently measured (peak data
output).
4. Press ON/OFF, if the unit does not display zero, select TR mode
and use the Zero Adjustment Pot. to make sure the display
reads zero.
5. Select Peak Mode (PP) or Peak Down mode (PD).
6. The blow counter counts the number of pulses
for a specified time, up to 9.9 seconds. The counter
works in PP mode only. Set the time duration by
using a pointed tool like a paperclip to push the
switches , right to increase, left to decrease.
7. Insert wrench drive securely into the sensor, hold
perpendicularly (not at an angle), and turn on
the tool to measure.
8. After taking measurement, press CLEAR to
zero the display for the next test.

SW-1SV-USB is a highly customized
Excel spreadsheet specifically
designed for capturing and analyzing real-time data from Cedar
torque instruments with a USB
port. SW-1SV-USB provides a running log of all measurements along
with a graph and statistical information including min, max, mean,
median, standard deviation, average
deviation and variance.
Requirements
1. PC computer with Windows XP or later and Excel 2000 or later.
2. CB-208 or CB-209 cable
Optional Data Acquisition Software SW-1SV-USB

Auto Power Off
To maximize the life of the battery, power will automatically shut
off after 10 minutes of non-use.
System Reset Button
When battery has been depleted completely and a recharge has
been executed, the system may not yet work. In this case, press the
System Reset Button .
Low Battery Indicator
“–L– –” will appear when tester needs to be recharged. Turn off
power.
IMPORTANT! Use the provided IMADA/CEDAR AC adapter/charger
exclusively and plug into the correct AC output. It takes 8 hours to
charge fully. Do not recharge for more than 12 hours. When it is
fully charged, make sure the AC adapter/charger is disconnected to
avoid overcharging.
In order to avoid high heat, explosion or toxic fumes, please note
the following precautions:
Be sure to use the provided AC charger exclusively.
Do not plug the charger into unspecified higher voltage.
Do not recharge until LOBAT icon appears.

Auto Zero Reset Switch for Peak or Peak Down mode
Rather than resetting manually for each test, the Automatic Zero
Reset can be programmed by using a paperclip to push the Auto
Zero Reset Switch .
As the Auto Zero Reset Switch is pressed (use a pointed tool,
like a paperclip end), the Automatic Zero Reset durations cycle.
(0.0C Þ 0.5C Þ 1.0C Þ 1.5C Þ 2.0C Þ 2.5C Þ 3.0C) Select the
desired duration. For example, 0.5C means 0.5 second and 0.0C
means MANUAL RESET. If a selection is not made within 3 seconds,
the cycle begins again.

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.
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 is available in PD, PP and C modes. In PD and PP modes peak
data is output when ZERO is pressed or activated by the AUTO ZERO
function. In C mode, the gauge outputs data continuously 180
data/second.
