The Martindale VT series Voltage Indicator and Proving Unit kit is packed with useful diagnostic test features and fully meets the requirements of GS38 and Proving Dead procedures. The tips of the probes on the VT25 are shrouded to meet GS38 standards and can be removed temporarily for access to deep or difficult to reach test points. The tester can detect voltages between 12v and 690v. Voltage levels are indicated by bright LED’s. The continuity Test (with buzzer) function makes the VT25 very useful in many diagnostic applications too. It can perform a Single Pole Phase Test, however, two-pole voltage indication should always be the preferred method when proving dead. The Phase Rotation test feature allows Phase to Phase voltage measurement and Phase Rotation is indicated on the unit via the “L” or “R” LEDs.
