Running a Defibrillator Test
51
(8) The DA-2006 will automatically sense the voltage rise across the internal 50 ohm
load and begin taking readings. After the sampling is done (100 ms) the unit will
compute and display the results.
a. The power pulse is available at the oscilloscope output in real time at
200:1 signal attenuation when in low range and 1000:1 signal attenuation
when in high range.
b. After the computation, the pulse is automatically played back at a 200:1
time base expansion (200 times slower) on both the ECG leads and the
Paddle plates. The signal level is 1 mV per 1000 Volts on Lead 1.
c. At the same time, the test results are sent to the printer.
(9) The Status line will change to indicate the various steps as they are being done.
(10) At the end of the process the results are continuously displayed in the Test
Results section of the MAIN SCREEN. They will remain there until another test
is performed, the range is changed or the power is turned off.
NOTE: Special note should be made of the “Delay: xxx msec” line in the
results. This will show the delay between the peak of the R-wave and the
start of the Pulse.
