Description
JDiag • Electrical detector P150
The JDiag electrical detector P150 is a multi-function professional circuit tester for vehicles operating on 6-30 V systems. Featuring a bright 160×128 DPI TFF color display and a long 6 m (≈20 ft) dual-cable reach, it enables repair technicians to automatically measure DC/AC voltage, resistance, diode feedback, frequency (10-200 kHz), and duty cycle (1-99 %). The built-in auxiliary ground lead allows safe component activation — fuel injectors, cooling fans, solenoids — without jumper wires.
Key benefits
- Automatic “smart” detection of voltage, resistance, and diode without mode selection upon start-up
- Circuit breaker protection with trip thresholds: 8 A (1 hour), 12 A (< 1 hour), 16 A (< 5 seconds)
- Rich signal diagnostics – frequency, duty cycle, injector waveform capture
- Robust design with wide operating range: −40 °C to 70 °C storage, 0 °C to 60 °C use
- Long dual cable setup reaches 40 ft total, simplifying testing across large vehicles or harnesses
Supported functions
Depending on vehicle compatibility the following functions are supported:
- DC voltage measurement
- AC voltage measurement
