Figure 7-2-1 Page to Be Measured after the Comparator Is Turned on



After the comparator is turned on, the "COMP" logo will appear at the top of the screen,

which means that the comparator function has been turned on at this time. Because

the comparator has been turned on and the system has started to run, the

discriminating symbol

is displayed on the screen, which is a normal interface.



means that the test clip or test pen is not properly connected to the

object under test. Please connect the test clip or test pen to the object under test

correctly to enter the state to be measured.

7.2.2 Example of Qualified Discrimination

Figure 7-2-2 Example of Qualified Discrimination Page



When the voltage or resistance measurement value is within the setting range of the

comparator, the judgment symbol

of the test value will be displayed on the screen,

indicating that the measured value is within the specification range. Only when the

resistance and voltage are within the range, the instrument will judge the total result
