Warnings and Messages
The Tester detects various conditions and shows a message on the display. The messages
have two categories: measurement warnings and system warnings. Measurement warnings
are warnings that are visible on the measurement screen and give indication that something
happened to the measurement.
The other category is system messages that occur with a popup to indicate a Tester problem.
Most of these messages are critical.
For every warning there is an indication of the level. This could be informative, a warning, or an
error. If an warning is critical, you cannot dismiss the warning. This warning continues to occur
when you reboot the Tester. For example, if one of the fuses is broken, the Tester is not
operable.
How to Zero the Test Leads
Test leads have a small amount of inherent resistance that can affect a measurement. Before
you do continuity or loop impedance tests, use the zero adapter to compensate for, or zero,
the test leads or the mains cord.
The Tester maintains a separate zero value for each continuity range and loop impedance test.
A unique zero is stored for each function. The
annunciator indicates when a zero value is
stored for the selected lead combination. For each continuity range, zeros are valid for both
polarities.
Note
Be sure the battery is in good charge condition before you zero the test leads.
To z e r o :
1. Select Z
I
mode.
2. Connect the mains line cord (or the test leads) to the Tester and the zero adapter. See
Figure 5.
