Fieldpiece ehdl1 Electronic Handle Modular Multimeter

Product Description

The FIELDPIECE ehdl1 is an electronic handle module designed for use with Fieldpiece modular test instrument systems. It provides voltage measurement capabilities with a resolution of 0.1 millivolts, supporting both DC and AC voltage readings. Accuracy for DC voltage measurement is rated at 0.5% of reading plus 1 digit, while AC voltage accuracy is 1.2% of reading plus 3 digits across a frequency range of 50 to 500 Hz. Overload protection is rated at 30 VDC or 24 VAC. Licensed HVAC technicians and field service pros use this handle as part of a modular diagnostic setup on residential and light commercial systems.

The ehdl1 fits into the Fieldpiece modular instrument platform, where a single handle accepts interchangeable accessory heads for different measurement tasks. This makes it practical for HVAC technicians who need compact, versatile test gear on service calls. It is suited for low-voltage control circuit diagnostics, including 24-volt control wiring common in gas furnaces, heat pumps, and split-system air conditioners.

Installation Notes

This instrument is intended for use by qualified HVAC technicians and electricians trained in safe electrical measurement practices. Always de-energize and lock out circuits before connecting or disconnecting test leads unless the procedure specifically requires live-circuit measurement. Follow NEC and local code requirements for working on energized low-voltage control circuits. Do not exceed the rated overload protection limits of 30 VDC or 24 VAC.
