Multimeter BLOW 9658# — analog ammeter with shunt, 10 A range

Multimeter BLOW 9658# is an analog ammeter with an internal shunt designed to measure direct currents up to 10 A. The instrument uses a needle indicator and a calibrated scale for immediate visual readings, making it suitable for straightforward current measurements, continuity checks and basic electrical diagnostics in automotive, household and light industrial environments. Its compact, panel-mount style and mechanical construction emphasize simplicity and reliability for routine tasks where a digital readout is not required.

Advantages

The analog display provides continuous, real-time needle movement for easy observation of changing currents without sampling lag. An integrated shunt enables direct measurement of currents up to the 10 A range without additional accessories. The device has a clear scale and mechanical pointer that are readable at a glance, and its uncomplicated design requires minimal setup and no batteries for current measurement. The robust construction is appropriate for environments where a basic, serviceable instrument is preferred.

Suitable for

• Measuring DC currents in automotive charging and starter circuits
• Basic electrical troubleshooting and continuity checks
• Verification of current draw in household appliances and small motors
• Light industrial process checks where simple ammeter readings are sufficient

Key specifications

• Measurement type: analog ammeter (needle indication)
• Current range: up to 10 A DC via built-in shunt
• Display: calibrated scale with mechanical pointer
• Power requirement: passive operation for current measurement (no internal battery for ammeter function)
• Mounting: panel or surface mounting suitable for workshops and control panels
• Typical accuracy: appropriate for basic diagnostics and monitoring (analog class-level performance)

How to use

Connect the multimeter in series with the circuit under test so that the measured current flows through the built-in shunt and the instrument. Ensure correct polarity when measuring DC current and secure wiring to the instrument terminals according to the device markings. Observe the needle movement on the calibrated scale to read the current value directly; allow the needle to stabilize for a representative reading. For continuity checks and simple troubleshooting, make sure the circuit is powered and use the ammeter only where permissible for direct current measurements up to the specified range.

Usage recommendations

Use the ammeter within its rated 10 A range and avoid overloads to prevent damage. For measurements where precision beyond basic diagnostics is required, consider comparative verification with a calibrated digital instrument. Regularly inspect connection points for corrosion or looseness and mount the instrument in a protected location to reduce exposure to mechanical shock and moisture.
