6.2.5 Checking frequency response
Apply +DC signal onto the amplifier’s input (2000 +/-0.5% µVpp / 150 Hz sine) from a ground independent
generator according to the table. DC must be +320, -320 mV.
The filter must be off.
Connect the patient cable according to the following tables and with the channel selector start the channels one-
by-one, and measure the signal amplitude or during 50 mm/sec *1 printing.
a/ In case of DC = -320 mV
The signal’s amplitude on the examined lead must be min. 1400 µV.
