5 Using the DL9110 / DL9118
5.1 Power On
To turn the DL9110 / DL9118 on simply rotate the rotary switch to the
required test position.
5.2 Battery Health Check
The DL9110 / DL9118 will automatically perform battery health checks
periodically or when a new test type is selected.
Note: When the battery symbol is flashing all tests will be inhibited
and the batteries should be replaced as described in section
8.4.
5.3 Remote probe (only supplied with DL9118)
The remote probe can be used in place of the standard 4mm red test
lead. When the remote probe is connected, the TEST button on the
probe performs the same function as the TEST key on the DL9110 /
DL9118. Either TEST button can be used to initiate a measurement.
5.4 Continuity Tests
Always ensure that the circuit under test is electrically
isolated.
Measurements can be adversely affected by impedances
of additional operating circuits connected in parallel or by
transient currents.
If the test probes are connected across a voltage of >30V
ac/dc then the DL9110 / DL9118 will automatically display
the voltage between the probes, the warning buzzer will
sound and the TEST key is inhibited.
Rotate the rotary switch until the Continuity test is selected.
When the continuity test is selected, the DL9110 / DL9118 will display
the user selectable test options for approximately 1 second; Buzzer,
Lead Zero and Auto Start. If the Buzzer or Lead Zero was previously
enabled then the icon will remain on the display when the continuity
test is selected.
