TORQUE MEASUREMENT
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 160
data/second.
Comport signal
8 data, 2 stop, no parity. Baud Rate: 19,200 bps.
Output Connector
USB A/B cable
Peak Data Output Format
[CAN] _ _ _ [SO] [value] _ [SI] [unit] [CR]
(_ _ _ is memory location)
[CAN]: ASCII control code 24
_: Space (code 32)
[SO]: ASCII control code 14
[value]: Output data with sign and decimal point. Plus sign
represents for CW torque and minus sign for CCW.
[Value] always occupy six locations and empty
locations will be filled with spaces.
[SI]: ASCII control code 15
[unit]: N*m _ _ _=N.m
kgf*cm = kg.cm
lb*in _ = lb.in
[CR]: ASCII control code 13 (Carriage Return)
Continuous Output Data Format
[CAN] [value] [CR]
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 ent
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.
SELECTING MEASURING MODES
Press ON/OFF to turn on. Press MODE to cycle modes GO, PP, PD or
C. Select desired measuring mode, which becomes the default mode.
GO Real Time, Display torque transient (no output or indicator).
PP Peak, Capture peak torque (peak data output, PP appears on
display).
PD Peak Down, Capture peak down value (peak data output, PD
appears on display).
C Continuous data output, Display and output torque tran-
sients (160 data/sec., solid green LED indicator).
