Elenco 3 1/2 Digit with Temperature - Manual (Page 24)

Note: Open-circuit voltage between measuring terminals is
approximately 1.5V (measuring current approximately 1.5mA).
Testing for Continuity
Caution
To avoid possible damage to the meter or to the equipment
under test, disconnect the circuit power and discharge all
high-voltage capacitors before testing for continuity.
Continuity is the presence of a complete path for current flow. The
continuity test features a beeper that sounds if a circuit is complete
(the resistance less than 120
Ω approx.). The beeper allows you to
perform quick continuity tests without having to watch the display.
The continuity function detects intermittent opens and shorts lasting
as little as 1 millisecond (0.001 second). These brief contacts
cause the meter to emit a short beep. Refer to Figure 12 for
continuity testing setup instructions.
