 1. The MEMS products are particulary sensitive of ESD (electro-static discharge), it's recommended to use grounded anti-static wrist straps and grounded anti-static mats before handling the products. 2. Make sure the driving voltage is 0V before and after operating. 3. when switching on the circuit, connect ' - ' (pin2) first, then ' + ' (pin 1) and upgrade voltage slowly. when switch off the circuit, power off '+' (pin 1) first, then ' - ' (pin 2). 4. Always take anti-static measures to storage the products when not in use. |
