What does it mean when my multimeter beeps?
When testing for continuity, a multimeter beeps based on the resistance of the component being tested. That resistance is determined by the range setting of the multimeter. If the range is set to 400.0 Ω, a multimeter typically beeps if the component has a resistance of 40 Ω or less.
What does 0 l mean on a multimeter?
On a digital multimeter, infinity reads “0. L.” On a VOM, “zero” means a closed circuit has been detected. The display needle moves to the far right side of an analog scale; “zero” reads “0.00” on a digital VOM.
How do I know if my multimeter fuse is blown?
If you try to measure the current with a blown fuse, you’ll probably notice that the meter reads ‘0.00’ and that the system doesn’t turn on like it should when you attach the multimeter. This is because the internal fuse is broken and acts as a broken wire or open.
What is the symbol of continuity in a multimeter?
diode symbol
Continuity: Usually denoted by a wave or diode symbol. This simply tests whether or not a circuit is complete by sending a very small amount of current through the circuit and seeing if it makes it out the other end.

Why does rapitest DM25 say 24 VDC?
Not sure about the other part of your message, but basically if the manual says, for example, there should be 24VDC between two points then touch them both with the meter on the correct settings and see what it says. By the way if the meters says -24 VDC instead of +24VDC then you just have the probes round the wrong way on the pcb.
What should I do if my rapitest DM25 lights flash?
The fault finding chart says to check the flue. clean (fitted new fan 2 years ago). So I fitted a new APS – but the fault remains – both lights flash. I’ve blow through the tubes and the tube that goes into the hampster wheel. to see if power (24 V DC) is at the relevant connectors.
How to measure 24 VDC with diynot DM25?
To measure 24 VDC… You then need to choose the next level up from what you want to measure, therefore select 200. Red probe goes in the hole with V next to it, it may share the same hole to measure resistance (the ohms sign) but if it doesn’t (not all meters do) then make sure it goes into the V for Volts hole.
