3.5 Continuity Measurements

M3500A uses 1 K Ω range for the continuity measurement. The meter
beeps when the test resistance is less than the threshold resistance. The
default threshold resistance is 10 , but you can set the threshold
resistance to anything between 1
by you is stored in a volatile memory and will be cleared after the meter
has been turned off. The source current for the continuity measurement
is 1 mA.
Warning! The maximum input voltage allowed is 1000 V. Applying
excess voltage may damage the meter and cause unpredictable
hazards.
How to measure the continuity
Selects input signal connections on front or rear panel.
Connect the test leads to the terminals as shown in Figure 3-2.
