Use your digital multimeter, data logger, or handle to measure parameters needed by HVAC/R technicians. Fieldpiece accessories work with meters that have mV (AC and DC) ranges and industry standard input jacks. Use the Fieldpiece deluxe test leads or the convenient AHDL1 adapter handle to connect any accessory head to most digital multimeters. The ACH4 works with the Fieldpiece "Stick meter, EHDL1 Electronic Handle, DL2 Data Logger, or any digital multimeter (with mVAC range) connected by Fieldpiece ADLS2 leads or AHDL1. USE IT YOUR WAY..
For most heads, set your meter to mVDC and read the LCD directly.
