Technical snapshot
Key DL429 measurement specs.
Core measurement ranges for modern HVAC/R electrical diagnostics, current checks, flame sensors, capacitors and temperature split testing.Advanced HVAC/R diagnostics
Measure current, voltage, temperature and control signals from one clamp meter.
The DL429 combines True RMS measurement, 600A AC clamp current, wireless app output and dual temperature inputs for professional heating, cooling and refrigeration diagnostics.
- True RMS wireless clamp meter for professional HVAC/R electrical testing.
- Measures up to 600A AC through the clamp jaw.
- Supports 750V AC, 1000V DC, resistance to 60MΩ and capacitance to 2000µF.
- Measures DC microamps from 0.1µA to 2000µA for flame sensor testing.
- Includes frequency, duty cycle, diode testing, continuity, NCV detection and LRA inrush.
- Dual temperature inputs with differential temperature readings.
What it helps check
Use the DL429 when a system needs more than basic voltage and current checks. It brings AC current, voltage, temperature split, control-signal and component testing together in one meter.
- Compressors, fan motors, contactors and standard HVAC/R electrical circuits.
- AC ductless mini splits, compressors, motors and control circuits.
- Flame sensors, capacitors, temperature split and system performance checks.
DL429 field guide
A better fit for advanced HVAC/R electrical work.
Where it earns its keep
Use it when standard clamp readings do not tell the full story.
- Compressor and motor startup checks where LRA inrush capture matters.
- HVAC/R service checks where current, voltage, capacitance and temperature split need to be compared together.
- Heating service work where flame sensor microamp readings and live electrical checks are part of the same job.
Wireless workflow
Use app output when the reading needs to be watched remotely.
Wireless output lets technicians view live readings from a compatible iOS® or Android™ device, which is useful when the meter is positioned inside equipment or when values need to be monitored during startup.
Electrical safety
Verify the setup before touching live circuits.
- Inspect the meter, leads and accessories before use.
- Use the correct function, jack and range for the measurement.
- Do not exceed the CAT III 600V rating or the stated measurement limits.
