Button Functions on the Amprobe 37XR-A
Using the Amprobe 37XR-A feels like stepping into serious territory. This meter packs a full spread of buttons, and once I got the hang of them, they made my bench work smoother and more efficient. Here’s how I work with each one:
- MIN MAX AVG – I press this to record minimum, maximum, and average readings over time. It’s a real bonus when I’m troubleshooting inconsistent voltages or tracking signal behavior.
- REL – The relative mode button is a personal favorite when I want to zero out the meter before comparing changes. Whether I’m isolating a small voltage drop or checking signal shift, this helps me focus only on the variation.
- RANGE – Like most pros, I don’t always trust auto-range. With this button, I set the exact range I need and get more stable, readable results especially when measuring fluctuating sources.
- HOLD – I’ve used HOLD more times than I can count. Perfect when the screen isn’t directly in view or when I need to double-check a number after disconnecting the probes.
- PEAK + / PEAK – – This feature helps me capture the highest and lowest points of a signal. I use it mainly in motor or signal testing, where quick spikes are easy to miss on a standard display.
- Yellow Logic Button – This activates the logic test functions, and I turn to it when checking TTL or CMOS logic levels super useful during board-level diagnostics.

Multimeters measure voltage by creating a circuit between the two points you’re testing and then measuring the current that flows through that circuit.
They do this by using a “multimeter probe.” You place one probe on one point of the circuit and the other probe on the other point of the circuit. The multimeter measures the current flow through the probes to get your voltage reading.
Q3.How easily can the continuity beep be heard in a multimeter?
It depends on the sound level of the environment and how sensitive the person’s ears are. Mostly it is a sound that you can hear easily.
