The comparator function compares the measured values with pre-set High and Low limit values for internal resistance and voltage level, and determines the range that the measurement should fall into. Then, according to the following conditions, switches ON the corresponding LED, and sounds an audible alert as shown in the table below for the WARNING and FAIL conditions.
