Step 1
The test works by sending an electrical current through the fluid, measuring the resistance, this then indicates the quality of the fluid on the LED readout scale. Check that the calibration is correct, if need be, reset the calibration as per the instructions.
Step 2
Dip the test bar into the fluid tank 2cms, push the blue test button in order to view the fluid condition, the LED readout will display the fluid condition and moisture level from 0 - 5%. When the test is finished clean the test head, fold back into the tester and store safely.
