Page 3: Introduction
Ch10~Ch22 (Figure 1) Single channel concept Via a SEEG 100E, the system produces arbitrary waveforms (streamed from the PC with digital to analogue conversion) at up to ±1V, which is then applied to a precision 500:1 divider to produce the voltages at up to ±1mV level (2mVpp). The SEEG 100E contains resistor/capacitor networks, dc offset, and relay switching to provide the full range of single channel performance tests in IEC standard. -

Single Channel EEG Test System | User Manual 2.7.1 Calibration procedure Parameter Nominal Method value, tolerance Input 620kΩ±1% This can be measured as follows: • impedance Set Main function to “Off” • resistor Set output to ch1 • Uncheck “620KΩ/4.7nF” Measure the resistance between ch1 and ch2 Input 4.7nF±5%... - Page 19 Single Channel EEG Test System | User Manual • Confirm all values are within 1% or 5µV of the set value • Note: The Fluke 8845A has suitable accuracy at 10mVpp but has borderline accuracy at 1mVpp and lower. An alternate method is to measure the output at BNC2 and then use the divider ratio above.

Move the main function mode to “Off” and then stops responding return to the function being used. If this does not work, close WhaleTeq software, disconnect the SEEG 100E module, reconnect the SEEG 100E module and re-start the SEEG 100E module. 4 Contact details WHALETEQ Co., LTD service@whaleteq.com | (O)+886 2 2596 0701...
