Measuring Current
The Analyzer can make dc only, ac only, and ac+dc
current measurements up to 10 mA. To make a current
measurement:
1. Press the softkey labeled Leakage from the
Point-To-Point menu.
2. Using  or  select between ac only, dc only, or
ac+dc measurement mode.
3. Insert test leads in the RED and BLACK 2-Wire
V/
Ω
/A jacks.
Place the leads on the two points the unknown current
may flow and read the measurement in the Analyzer’s
display.
Simulating ECG Waveforms
The Analyzer is capable of generating various waveforms
on the applied parts connection posts. These signals are
used to test the performance characteristics of ECG
monitors and ECG strip printers. See Figure 32 for proper
connections between the Analyzer and an ECG monitor.
To access the ECG Simulation Waveform menu shown in
Figure 31, press . From this menu, a number of
different waveforms are selected through F1, and the rate
or frequency of the waveform is selected through F2.

Figure 31. ECG Waveform Simulation Menu
To select one of the predefined waveforms, press the
softkey labeled Wave Form. A scroll box with  next to it
appears above the softkey label. Use  or  to scroll
through the different waveforms.
For all waveforms except VFIB and Triangle, the rate or
frequency of the waveform is adjusted through the softkey
labeled Frequency or Rate. For some waveforms, there
are more than two frequency or rate selections. For those
waveforms, pressing the softkey labeled Frequency or
Rate will open a scroll box above the softkey label with 
next to it. Use  or  to select the frequency or rate. For
those waveforms that have only two frequency or rate
selections, the softkey labeled Frequency or Rate acts
as a toggle, where each press of the softkey switches to
the other value.
