Overview
The ZCE838 Series is a portable calibration and testing device designed to generate a wide range of standard and custom waveforms for calibration, performance evaluation and troubleshooting of ECG, EEG and patient monitoring equipment.

Main capabilities

• Waveform outputs: square, sine and triangle waves, simulated ECG waveforms, heart-rate (HR) signals, monitor-derived HR signals and pacing pulses.
• Abnormal and arbitrary waveform generation with continuously adjustable amplitude and frequency for ECG simulation and general-purpose signals.
• Built-in standard calibration protocols that automatically switch waveform type, amplitude, frequency, lead connections and related parameters according to calibration procedures.
• Automatic configuration of auxiliary calibration circuits (lead switching, skin impedance, polarization voltage, internal attenuators) to avoid manual rewiring.
• Universal ECG connector supporting plug-in and snap-fit connections: compatible with 2 mm, 3 mm, 4 mm leads and snap-fit lead wires.
• 7-inch color LCD with capacitive touchscreen for intuitive operation.
• Internal lithium battery enabling portable field and laboratory use.

Applications

• Routine calibration and verification of electrocardiographs (ECG machines), electroencephalographs (EEG), patient monitors and wearable cardiac devices.
• Troubleshooting, performance evaluation and functional testing of monitoring systems using customizable normal and abnormal waveform simulation.

Notes

• Amplitude and frequency adjustments are continuous to support precise testing scenarios and custom waveform creation.
• The universal connector and automatic auxiliary-circuit configuration simplify connection to a variety of devices without manual rewiring.
