Multimeter InLine 43127 with touch pad, illuminated LED display 62x50 mm, CAT III/CAT IV, AA battery

The InLine 43127 handheld multimeter features a touch pad and an illuminated LED display measuring 62 x 50 mm. Designed for tasks that require overvoltage category protection, this battery-powered meter accepts a single 1.5 V AA cell and supports CAT III and CAT IV rated environments. The instrument offers electronically selected measuring ranges without mechanical range switching, reducing sensitivity to dirt and wear while providing clear numeric readings on a backlit dual-value display.

Advantages

The touchpad operation enables smooth, contact-based selection of measurement functions and ranges without mechanical switching, improving reliability in dusty or harsh conditions. A large, bright illuminated LED display presents two values simultaneously for easier comparison and faster readings. Compact, handheld construction and AA battery power make the unit portable and simple to maintain. Rated for high overvoltage categories, the device is suitable for industrial and residential electrical work where enhanced safety is required.

Suitable for

• Electrical installation and commissioning in buildings and industrial sites
• Maintenance and troubleshooting of power distribution systems
• Technician field testing where CAT III/CAT IV protection is needed
• Routine checks of circuits, voltage levels and continuity

Key specifications

• Display type: illuminated LED dual-value display, 62 x 50 mm
• Operation: touch pad (no mechanical range switch)
• Overvoltage categories: supports CAT III and CAT IV applications
• Power source: single 1.5 V AA battery
• Measurement range selection: electronic via keys
• Design: handheld, compact form factor for field use

How to use

Install one 1.5 V AA battery in the compartment and switch the multimeter on using the touch pad. Select the desired measurement function and range by tapping the corresponding key; the instrument will electronically select the appropriate range and display results on the backlit LED screen. Hold the meter securely and connect probes to the circuit under test following standard safety procedures for CAT III/CAT IV environments. Read primary and secondary values directly from the dual-value display and switch functions as needed by touching the relevant keys.

Recommendations

Use appropriate protective equipment and follow local safety regulations when working on live circuits. Ensure probes and connectors are rated for the target voltage category, and replace the AA battery promptly when display brightness or measurement response decreases. Store the multimeter in a dry, dust-protected location to maintain touch pad responsiveness and prolong service life.
