Connection between SKX-2000+ and ECG equipment 1. Connection method of ECG machine: RA-R (right hand), LA-L (left hand), LL-F (left leg), RL-RF (N) (right leg), C1-C6 (V1-V6) chest lead; 2. Connection method of monitor: RA-right hand (white), LA-left hand (black), LL-left foot (red), RL-right foot (green), C1-C6 chest lead (brown); 3. Three-lead connection method: RA-right hand (white), LA-left hand (black), LL-left foot (red); or when the acquisition lead is II; RA-right hand (white), LL-left foot (red), RL-(reference ground, feedback point); or when the acquisition lead is I; RA-right hand (white), LA-left hand (black), RL-(reference ground, feedback point); 4. Two-lead connection method: Please connect RA-LL when the acquisition lead is II, and please connect RA-LA when the acquisition lead is I; Notes for SKX-2000+ 1. The SKX-2000+ series ECG simulator can calibrate ECG devices. The calibration lead is limited to II, that is, the signal amplitude output from the RA-LL end. Connect the RA lead of the ECG device to the RA end of the simulator, and the LL lead to the LL end of the simulator. The signal collected by the ECG device meets the signal amplitude range of 0.1mV-4mV set in the software; 2. ECG waveform The waveform amplitude is fixed and cannot be changed; 3. If you calibrate other leads, please calibrate according to the following methods: A. I lead calibration: please connect the lead wire RA to the RA end of the simulator, and the lead wire LA to the LA end of the simulator. At this time, the signal collected by the ECG device is the calibration signal of the I lead; B. C lead calibration: please connect RA, LA, and LL in parallel to the RA end of the simulator, and C1 or other chest leads to the LL end of the simulator. At this time, the collected C1 (or other chest leads) is the standard calibration signal; 4. Regarding the detection method of bias voltage, when testing the forward bias, please select the sine waveform and connect the RA of the ECG device to the LL end of the simulator, and the LL of the ECG device to the RA end of the simulator for positive bias voltage testing; when testing the negative bias voltage, please select the sine waveform and connect the RA of the ECG device to the RA end of the simulator, and the LL of the ECG device to the LL end of the simulator for negative bias voltage testing; 5. When there is no key operation for one minute, the screen will automatically turn off. Press any key to restore the screen. After the screen turns off, the indicator light starts to work and flashes every 5 seconds; the screen restores After the display, the indicator light stops flashing; SKX-2000+ simulator standby working time 1. When the battery level is displayed as 0%, the simulator can automatically shut down after working for another minute. If any button is selected, the timed shutdown will be delayed until it automatically shuts down after no button is pressed within 1 minute; 2. When the battery level is displayed as 10%, the simulator can automatically shut down after working for another 5 minutes. If any button is selected, the timed shutdown will be delayed until it automatically shuts down after no button is pressed within 5 minutes; 3. When the battery level is lower than 0%, the simulator cannot be turned on again;
