Display reminding lamp is bright), two electrodes to be measured and electrode test cable connection are got well and electrode pair is formed, measurement is then pressed and starts
Key, self-clocking at once, while lamp goes out.After about 60 seconds, impedance display warning light is bright again (to start warning light while measuring
It is bright), the reading of numerical monitor is exactly the impedance value of the electrode pair this moment, and unit is Ω.
Warning light and impedance display warning light one can not also be started by measurement start key, i.e. not self-clocking, then measurement
It is straight bright, access after electrode pair to be measured about 60 seconds, shown numerical value is exactly the impedance Ω numbers of tested electrode pair.
Imbalance function key is pressed, it is to be measured by two when measurement startup warning light is bright (while display reminding lamp of lacking of proper care is bright)
Electrode is got well with electrode test cable connection and forms electrode pair, and measurement start key is pressed at once, and (measurement starts warning light and imbalance
Display reminding lamp goes out together, starts simultaneously at self-clocking).Display reminding lamp of being lacked of proper care in subsequent 60-90 seconds is bright (after 60 seconds
It is bright always that measurement starts warning light), now the reading of numerical monitor is exactly the offset voltage value of tested electrode pair, and unit is mV.
To ensure measurement accuracy, tested electrode pair should be put into shielding box and measured.Comprise the following steps that：Press and make an uproar
Sound function key, when measurement startup warning light is bright (while noise display reminding lamp is bright), by two electrodes and electrode test to be measured
Cable connection is got well and forms electrode pair, and electrode pair is put into shielding box, cover lid press at once measurement start key (measurement is opened
Dynamic warning light goes out together with noise display reminding lamp, starts simultaneously at self-clocking).Noise is shown in subsequent 60-360 seconds
Warning light is bright (measurement startup warning light is bright always after 60 seconds), and now the reading of numerical monitor is exactly the noise electricity of tested electrode pair
Pressure value, unit is μ V.
Each tested electrode pair is serially connected with electrode test cable (quantity is serially connected with all electrode pairs,
Its voltage summation is limited no more than 1.5V, and does not exceed 30 pairs), it is connected on the 200nA binding posts in the lower right corner.Press the work(of resistance to stream
Energy key, the display reminding of resistance to stream lamp is bright always, measures each pair electrode with electrode test cable, reading now is exactly respective electrode pair
Starting offset voltage, then press bias current key (200nA binding posts above), the biasing up to more than 8 hours can be carried out
Electric current tolerance level is tested.Afterwards every 30 minutes, instrument sends several seconds prompting sound and each electrode pair is measured with reminding, that is, uses
Electrode test cable measures each pair electrode, the imbalance electricity of its show value each period that is exactly the electrode pair under bias current effect
Pressure, unit is mV.During measuring twice, the test of other projects can be carried out.Biasing electric current key has been pressed in resistance to stream off-test.
Wherein, offset voltage of each electrode pair under bias current effect is tested except with addition to resistance to stream function key, it is also possible to lost
Tune, defibrillating function key.If electrode test cable carries out other index tests and inconvenience is used, available digital universal meter is carried out
Measurement.
Two electrodes to be measured and electrode test cable connection are got well and electrode pair is formed, defibrillating function key is pressed, defibrillation shows
Show that warning light is bright always, while defibrillation startup warning light is bright.Stablize more than ten seconds, defibrillation start key is pressed again.Thereafter 5
Second, 15 seconds, 25 seconds, 35 seconds when, defibrillation sequential warning light bright 1 second successively, write down warning light it is bright when show value, 4 write down
Individual numerical value is exactly that the electrode pair is starting the magnitude of voltage by the corresponding time after simulating defibrillation, and unit is mV.Carried when defibrillation starts
When showing that lamp is bright again, defibrillation start key is pressed at once, is carried out defibrillation next time and is tested.So test, is total to by rower regulation each pair
Carry out 4 times.
When being tested, electrode pair to be detected can be divided into two groups, first group by " impedance before imbalance → defibrillation →
The order of impedance after defibrillation → defibrillation " is tested.Second group of sequential testing by " noise → impedance → resistance to stream ".Can be simultaneously
To two arrays of electrodes to detecting, to save the time.
