TORQUE MEASUREMENT
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 acciden-
tally changed.
3. Select among the following
Measurement Modes (For normal test-
ing, 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 analyz-
ing real-time data from Cedar
torque instruments with a USB
port. SW-1SV-USB provides a run-
ning log of all measurements along
with a graph and statistical infor-
mation 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
