## Summary description

Analog clamp ammeter BLOW model 51-020# provides current measurement up to 20 A using a side-opening clamp and an analog pointer display. Designed for basic electrical diagnostics and circuit checks, it measures AC/DC currents where applicable and offers portable, handheld operation for field technicians, electricians and hobbyists.

## Long description

The BLOW clamp analog ammeter 51-020# is a handheld measuring instrument for measuring electrical current up to 20 A. It features a side-opening jaw for quick clamping around conductors and an analog pointer display that provides a direct visual reading of current levels. The device is intended for basic diagnostics, circuit verification and quick spot checks in residential, commercial and light industrial electrical work.
Advantages
The side jaw design allows fast access to conductors in confined spaces without disconnecting wiring. An analog pointer display gives continuous, easy-to-interpret feedback of changing current values. Compact, lightweight construction supports portable field use and simple one-handed operation. The instrument's range up to 20 A covers common household and small-installation current measurements.
Suitable for
Measuring AC and DC currents in household circuits and appliances (within the specified range)
Quick verification of wiring and loads during installation and maintenance
Field checks by electricians, service technicians and hobbyists
Key specifications
Maximum measurable current: 20 A
Display type: analog pointer
Jaw orientation: side-opening clamp
Form factor: handheld, portable
How to use
Place the instrument in a stable position and ensure the meter is set to the appropriate current range before measurement. Open the side jaw and clamp it around a single conductor only; do not clamp around multi-core cables or grounded bundles. Read the current value from the analog pointer against the scale. For DC measurements observe correct polarity indications if provided by the instrument. After use, open the jaw, remove the meter from the conductor and store it in a dry, dust-free location.
Usage recommendations
Verify that the expected current does not exceed the instrument's maximum rating before measuring. Wear appropriate personal protective equipment and follow local electrical safety procedures when working on live circuits. Avoid exposing the meter to moisture, excessive heat or mechanical shock to maintain measurement accuracy and device longevity.
