Capture Test - Abbott Merlin PSA EX3100 Help Manual

To save a lead impedance measurement, select the impedance button. You can update a lead
impedance measurement for each channel as many times as desired. Up to five measurements
for each channel are saved and can be included in the PSA report. Once five measurements for a
single channel are saved, the next measurement retrieved for that channel replaces the oldest
saved measurement for that channel.
NOTE: To obtain the most accurate lead impedance measurement, ensure that the Pulse
Amplitude is set to a minimum of 2.0 V.
