Connect the output leads of the PIE 311Plus to the inputs of the device being calibrated.
Instantly output your SPAN and ZERO output settings by moving the EZ-CHECK switch between HI
and LO. You may also select any third output setting (such as mid-range) using the SET position on
the EZ-CHECK switch. The output is adjusted in 0.01 Ω increments by turning the knob
e
. Press
and turn the knob for faster dialing with 1.00 Ω increments.
