Fluke FLUKE-T150/PRV240 Proving Unit 0.005mA 6/690 V LCD

This proving unit verifies absence and presence of voltage in low- and fixed-voltage electrical systems, providing a portable battery-powered check before maintenance or diagnostics. It is designed for on-site use in industrial and commercial environments and operates from internal cells to deliver a clear, immediate indication of live circuits via multiple signalling methods.

• 240V output with LCD display for clear voltage indication
• Low test current 0.005mA minimises circuit influence during proving
• Battery powered using 4x AA batteries for field portability
• UK plug proving unit GS38 format for compatibility with British outlets
• Compact proving unit 11.7cm 230g for easy tool-belt carry
• Built-in tactile, audible and Visual indicators to confirm presence

• Suitable for pre-work verification on distribution boards and panels
• Ideal for electricians carrying out isolation checks on site
• Used for proving instruments and test equipment functionality before use
• Can be used for safe verification in installation and maintenance tasks

It uses four AA alkaline cells and the runtime depends on indicator use and frequency of tests

It is rated to operate between -10°C and 50°C, so performance should be verified outside these temperatures.

The proving unit features a UK GS38 plug configuration allowing direct connection to UK socket outlets or compatible adapters.

The LCD is backlit to improve readability in dim environments while tactile and audible signals provide redundant confirmation.
