## At a glance

- Backlit LCD is intended to aid use in dimly lit areas.
- Supports AC and DC voltage, DC current, resistance, diode and continuity checks.
- 1.5V and 9V battery modes are described as detecting and displaying battery status automatically.
- Data hold, auto shutoff, continuity buzzer and low-battery indication are listed.

## Pros

- A useful spread of measurements for basic household checks and automotive electrical troubleshooting.
- Dedicated 1.5V, 9V and 12V battery test modes add a practical battery-checking option.
- The backlight and continuity buzzer can help with checks where visibility or audible feedback is useful.

## Cons

- It cannot test AC current, which rules it out for jobs that specifically require that measurement.

## Before you buy

- The manufacturer says the meter cannot test AC current. The listing identifies CAT III 300V and claims double-fuse and silicone-cover protection, but these are manufacturer claims and do not establish suitability for every electrical task. Set the meter correctly before testing.

## In the box

- Multimeter (Included)
- Test leads \(1 pair\) (Included)
- User manual (Included)
- Batteries (Check selected pack): Mentioned in a feature description but not in the explicit included-components list. Check the selected listing.

## A good fit for

- DIY users checking household electrical issues, batteries or automotive circuits within the listed measurement functions.
- Hobbyists who want a compact meter with a backlit display and continuity buzzer.

## Less suited to

- Buyers who need AC-current measurement or a meter for tasks beyond its listed capabilities.

## Customer feedback

Customer feedback describes the meter as straightforward to use, compact and useful for DIY, with reported praise for readings, accuracy, build quality and the display. These are customer perceptions, not independent performance verification. The generally positive rating profile offers a favourable signal, but ratings alone do not establish measurement accuracy or suitability for tasks such as AC-current testing, which the listing says is unsupported.
- Positive themes: Customer feedback highlights ease of use, compact size, functionality and versatility.
- Positive themes: Customers report positive impressions of accuracy, build quality and the display.

## Frequently asked questions

### Can the AM33B measure AC current?
No. The listing specifically says this meter cannot test AC current. It lists AC and DC voltage, DC current, resistance and diode measurement.
### What battery types can it test?
The listed battery test modes are 1.5V, 9V and 12V. The description says the 1.5V and 9V modes automatically detect and display battery status.
### What is included?
The manufacturer’s included-components list names one multimeter, one pair of test leads and one user manual. A feature description also mentions batteries, but batteries are absent from that explicit contents list, so check the selected listing.
### Does it have a backlit display and continuity buzzer?
Yes. Both are listed features, along with data hold and auto shutoff.
