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.
