TORQUE MEASUREMENT
IMPORTANT! Use the provided AC adapter/charger exclu-
sively and plug into the correct AC output. It takes 8 hours to fully
recharge. Do not recharge for more than 12 hours. When fully
charged, disconnect the AC adapter/charger to avoid overcharging.
In order to avoid high heat, explosion or toxic fumes, please note
the following precautions:
1. Be sure to use only the provided AC charger exclusively.
2. Do not plug the charger into unspecified higher voltage.
3. Do not recharge until LOBAT icon appears.
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.
RS-232C Serial Output
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.
RS-232C Signal: 8 data, 2 stop, no parity. Baud Rate: 9600 bps.
