The Sensor Tester enables the sleep tech to verify the proper operation of many types of physiological sensors, electrodes, and cables used in the sleep lab.
The AC channel conveniently tests the operation of Piezo Crystal and Film Effort Sensors, Piezo Snore and Movement Sensors, and RIP/Inductive Sensors as well as any other sensor producing signals in the mV range.
The impedance channel will turn on the UP arrow light for resistance under 50 ohms. The results are high enough to show proper operation of all standard leads and electrodes, yet low enough to prevent showing GOOD" on a bad cable. The Sensor Tester battery should last for several years of normal use.
