How To Use Your Multimeter
Optional Accessory Heads
Fieldpiece accessory heads convert a
parameter into a millivolt signal. For example,
the ATH3 converts one °F into one millivolt DC.
Set the multimeter to read millivolts DC. Any
digital multimeter with a mVDC range and
industry standard jacks can be used with
Fieldpiece accessories. The only exception is
the ACH current clamp which requires the
meter to be set to read AC millivolts.
Use Fieldpiece deluxe test leads (model
ADL2) or the Fieldpiece handle/adaptor (model
AHDL1) to connect any head to a DMM.
Selecting Ranges
For all ranges and functions choose a range just above the value you expect. If display reads "OL"
(overload), select a higher range. If display shows less than three numbers, select a lower range for
better resolution.
Select AC or DC volts and amps ranges as appropriate.

Resistance
There are two ways to measure current using the LT17. To safely measure high currents, use the
Fieldpiece ACH, (or any other current clamp which converts amps to millivolts). To measure
microamps or milliamps, use the com jack and the jack on the lower left labeled mA. Do not
attempt to measure currents over 20mA.

Temperature
Insure the temperature being measured is
stable. Maintain good contact between the
thermocouple and what's being measured. Set
the meter on the 200
