CHECK readings using Newton-Meters and Kilowatts

The ZERO and CHECK positions of the computer function switch provide quick checks to determine whether the horsepower computer is operating properly. Proper readings indicate that the major portion of the computer is working correctly. Note that the Load Cell sensor circuits and the RPM pickup circuits are NOT tested in the ZERO and CHECK modes.

With the dynamometer at rest and the computer function switch set to “RUN”, the speed and power displays should show zero (“0”). The torque display may show some small value --- typically less than +/- 3 Ft.-Lbs (4 N-M). The % torque rise display reading depends on whether or not the reference torque has been set and if so, to what value – so the reading of this display should be ignored at this time. See also the section below.

System Power LED:

The system power LED (Light Emitting Diode) is located on the front panel of the unit, just to the left of the computer function switch.

This green LED indicates that power is applied to the unit and the unit is turned “ON”.

If this light is slowly flashing ON and OFF, this indicates that the power supplied to the unit is inadequate (voltage is too low or too un-steady) and that the readings produced by the unit are likely in-accurate as a result.

Torque Set Switch:

The reference torque set switch is located on the front panel of the unit – just to the right of the computer function switch. Your unit may (as an option) be equipped with a remote torque set switch. This switch is located remotely from the horsepower computer but functions the same as the torque set switch.
