The analyzer is powered by the vehicle's battery. For testing purposes, the analyzer clamps must be properly attached to the battery during testing. (The red clip indicates the positive terminal and the black clip indicates the negative terminal, which must be attached accordingly to the battery terminals. 2. Turn on and enter a. Press the power button for 1 second. b. The screen illuminates and the Bee alarm sounds a "B". The screen displays the moving digits, all test indices, and the low battery warning index. c. Press "OK" to enter the CCA (Cold Cranking Ampere) value entry step. d. The third digit to the right of the four-digit index flashes; this indicates that the index digit can be changed using the UP (increase) or DOWN (decrease) function button. Press the UP (increase) or DOWN (decrease) function button until the correct digit is displayed and move to the next digit to enter the value by pressing "SEL". e. The units digit to the right of the four-digit number increments by 5 units each time; the other digits are carried over.) Once a unit is added. F. Once the input steps are complete, press "OK." The analyzer will begin test mode for 10 seconds. The Bee alarm will continue to emit "Be" sounds when test mode is closed. Press any button to stop the "Be" sounds. If the battery voltage is too low, the "low" sign in the bottom left corner of the screen will flash. Please recharge the battery and test again.
