For DC voltage and currents, set the meter to the DC parameter instead of AC as shown to the left. For all ranges and functions choose range just above value
you expect. If display reads "OL" or "-OL" (overload), select a higher range. If display shows less than three numbers, select a lower range for better resolution.

Optional accessory heads

Fieldpiece accessory heads convert the desired
parameter into a millivolt signal. For example, the
ARH4 converts one °F/°C into one milli-volt DC.
The multimeter must then be set to read millivolts
MFD
DC. One exception is the ACH4 current clamp
which must be set to read AC millivolts. Any digital
multimeter with these scales can be used in con-
junction with Fieldpiece Accessory Heads.
Use Fieldpiece deluxe silicone test leads
(model# ADLS2) with removable probe tips to use
the accessory heads with the LT17A.
