# AstroAI CM2K0R 2000-Count Digital Clamp Meter

Digital: AstroAI CM2K0R is a 2000-count clamp meter for AC current measurement and AC/DC voltage, resistance, capacitance, continuity, diode and live-wire testing. Its jaw measures AC current only, so it is not suited to DC current measurements.

## At a glance

- The clamp measures AC current only. Use the test leads for voltage and other supported measurements, not the clamp jaw.
- Listed measurements include AC/DC voltage, resistance, capacitance, continuity, diode and live-wire tests.
- NCV gives audible and visual indications for detected AC signals, with different alerts described for weak and strong signals.
- Data hold, max/min, a backlit LCD, flashlight, continuity buzzer and auto shut-off are listed.

## Pros

- Combines clamp-based AC current measurement with test-lead voltage and component checks.
- NCV, backlight and flashlight can help when checking circuits in dim areas.
- The listing specifies auto-ranging and includes data hold and max/min functions.

## Cons

- The clamp cannot measure DC current.

## Specifications

### Identity

### Functions and operation
- Current measurement limitation: This CM2K0R clamp meter can not test DC Current.
- Non-contact voltage indication: When the Meter senses a weak AC signal, the green indicator light will come on and the buzzer will emit a slow, audible beep. when the Meter senses a strong AC signal, the red indicator light will come on and the buzzer will emit a quick beep
- Automatic shut-off: If the meter is not in operation for 15 minutes, it will turn off automatically.
### Power and battery
- Power configuration: Battery Powered
- Batteries required: 2 AAA batteries required.
- Battery inclusion claim: Two 1.5V AAA batteries are included in the package
### Dimensions and installation
- Dimensions listed: 6.8 x 2.9 x 19.5 centimetres
- Weight listed: 415 g
- Colour: Red

## Before you buy

- The listing's stated maximum AC current conflicts with its detailed measurement range. Verify the range and accuracy for the exact unit before relying on them.
- The listing gives a maximum AC current of 2000 A in one detail, but its specifications list ranges only up to 400A. It also reports 415 g in product details versus approximately 203g in its technical description, and differing dimension formats. Confirm these details for the selected listing. The instructions say to centre one conductor in the jaw and never clamp the entire power cord. The clamp jaw measures current only. Accuracy claims are manufacturer-listed specifications, not independently verified performance.

## In the box

- Clamp multimeter (Included)
- Test leads (Included)
- Storage bag (Included)
- User manual (Included)
- Two 1.5V AAA batteries (Check selected pack): Mentioned in a feature statement, but omitted from the included-components list.

## A good fit for

- DIY and household circuit checks where AC current, AC/DC voltage and basic component tests are needed.
- Users who want NCV indication, a backlit display and a flashlight in a battery-powered meter.

## Less suited to

- Users who need clamp-based DC current measurement.
- Buyers requiring a confirmed current capacity or weight before purchase without checking the conflicting listing details.

## Customer feedback

Customer feedback reports that the meter works for many users’ circuit-testing needs and is appreciated for functionality and perceived value, while some users raise concerns about accuracy, particularly current readings. That criticism matters for a meter whose clamp is intended for AC current. The listing’s current range is itself inconsistent, so buyers needing dependable readings should verify the range and validate readings for their application rather than treating either customer impressions or manufacturer specifications as confirmation.
- Positive themes: Customers report that the device meets their circuit-testing needs.
- Positive themes: Feedback describes the product as functional and good value.
- Negative themes: Some customers report inaccurate readings, including current readings they consider substantially off.

## Frequently asked questions

### Can the AstroAI CM2K0R measure DC current?
No. The listing explicitly says this model cannot test DC current. Its clamp measures AC current.
### What measurements does it list?
The listing names AC current, AC/DC voltage, resistance, capacitance, continuity, diode and live-wire tests. NCV is also described.
### How should the clamp be used for current?
Clamp around one wire, not the whole power cord, and centre the conductor in the jaw. The jaw is for current measurement, not voltage.
### What accessories are listed as included?
The manufacturer’s included-components field lists test leads, a storage bag and a user manual. A feature statement also says two AAA batteries are included.
