Fluke PRV240 – Overview The Fluke PRV240 is a portable proving unit designed to supply a known 240 V source (AC or DC) to verify that your multimeter or test instrument is functioning correctly before and after live measurements. This “Test Before Touch” method helps confirm instrument integrity without depending on external live sources. The unit is compact, battery-powered, and intended for safe, routine verification of measurement tools. Key Features Provides 240 V AC and DC output to verify test instrument functionality Recessed contacts activate only when probes are fully inserted Single LED indicator confirms proper operation Long battery life—capable of thousands of verification cycles per battery set Compact, pocketable design Includes magnetic hanging strap for convenience Designed to meet compliance and safety protocols in electrical maintenance Technical Specifications Model: Fluke PRV240 Output Voltage: 240 V AC RMS or 240 V DC ±10 % Load Requirements: ≥1 MΩ load for output; typical LoZ detection >3 kΩ load Minimum Output (for LoZ): ~50 V AC LED Indicator: On when output voltage is present Battery: 4 × AA alkaline Battery Life: ~5,000 test cycles (5 seconds each) with >1 MΩ load Operating Temperature: –10 °C to +50 °C Operating Humidity: 0–90 % (0–35 °C); 0–70 % (35–55 °C) Dimensions: 117 × 74 × 28 mm Weight: ~0.23 kg (with batteries) Safety: Conforms to IEC 61010-1 and IEC 61010-2-030 Warranty: 1 year Applications Verifying that multimeters and testers are functioning correctly before live measurements Performing “Test Before Touch” protocols in electrical safety procedures Routine equipment checks in maintenance and safety programs Enabling safe validation of measurement instruments in field and workshop settings Why Choose Fluke PRV240 Provides a known, reliable voltage source for instrument verification Simple and intuitive to use with LED indication Compact and durable for field use Helps enforce safety procedures by validating tester performance Order Now The Fluke PRV240 Proving Unit is available and ships worldwide.
