Using the
To measure low resistances with the Meter, position the rotary
switch to Y. This function has a single range and R is
therefore disabled when the Meter is in the Y function.
Only the relative and relative percent functions work with the
Y function. Press the softkey labeled Menu to access these
two functions.
Testing for Continuity
Continuity is the presence of a complete path for current flow.
The continuity function detects intermittent opens and shorts
lasting as short as 1 ms. The Meter uses three indicators for the
absence and presence of continuity: a resistance reading, an
open/short indicator, and a beeper.
The resistance reading is simply an ohms function measurement.
However, for continuity transitions that are very short, the slow
To avoid damaging the circuit under test, be aware
the Meter sources current up to 10 mA at an open
circuit voltage up to 20 volts.
To avoid possible damage to the meter or to the
equipment under test, disconnect circuit power
and discharge all high-voltage capacitors before
testing continuity.

measurement response of the Meter will not appear in the digital
display. Therefore, the continuity function uses a graphical
indicator for the presence or absence of continuity. Figure 16
shows the short and open continuity indication.
To perform a continuity test, position the rotary switch to
set up the Meter as shown in Figure 17. Press the softkey
labeled j. In continuity, a short means a measured value less
than 8 % of full scale for the 500
other resistance ranges.
The Meter operates in manual range only while the
continuity function is selected.
