## Long description

Analog ammeter BLOW 51-530# is a compact handheld instrument designed to measure direct current up to 30 A using an integrated shunt. The device offers a needle-type analog display with a clear graduated scale and a rugged portable housing for field use. Its simplified presentation of current values makes it suitable for quick checks in automotive systems, workshop equipment and basic electrical installations where fast, visual assessment of current is required.
Advantages
The analog display provides continuous needle movement for instant reading of current changes without the need for power or complex setup. The built-in shunt allows safe measurement of currents up to 30 A while keeping the instrument compact. A durable enclosure and straightforward front panel make the ammeter easy to operate during on-site diagnostics and routine maintenance tasks.
Suitable for
 Quick current checks in automotive electrical systems
 Workshop diagnostic measurements on motors and electrical assemblies
 Basic installations and maintenance in small electrical projects
 Field troubleshooting where portable, non-digital indication is preferred
Key specifications
 Measurement type: direct current (DC)
 Measurement range: up to 30 A
 Indication: needle-type analog pointer with graduated scale
 Shunt: built-in low-resistance shunt for high-current measurement
 Form factor: handheld, compact housing suitable for portable use
 Operating environment: workshop and field diagnostics
How to use
Connect the ammeter according to standard series measurement practice, ensuring the instrument is placed in series with the load whose current you intend to measure. Verify correct polarity before applying current to prevent reverse deflection of the needle. Position the shunt and connections securely and read the pointer value on the graduated scale while the circuit is energized. After measurement, disconnect the instrument and store it in a dry place.
Usage recommendations
For accurate readings and safe operation, ensure connections are tight and contact points are clean. Avoid measuring currents above the rated 30 A to prevent overheating of the built-in shunt. Use the device in environments within typical workshop conditions and protect it from prolonged exposure to moisture or strong mechanical impacts.
