Humidity Measurement Instrument operating instructions

1. Specification parameters of HW series

4. Safety precautions

(1) Please read this manual carefully before use, as wrong operation may damage the machine or cause serious accidents;

(2) The temperature and humidity sensor is a vulnerable component. When using it, handle it with care and operate with caution;

5. Tips for use

(1) Do not use sharp tools instead of fingers to operate keys.

(2) This instrument can only be used as a temperature and humidity meter.

(3) Do not use the instrument where water, oil or other liquids are splashed, and store the instrument in a cool, dry place without vibration.

(4) Do not use the Torque Tester where water, oil or other liquids are splashed, and store the Torque Tester in a cool, dry place without vibration.

(5) Please use the matching charger to charge. The red light is on when charging, and the battery is fully charged when the green light is on. It can be charged at the same time during use. Normal charging takes about 4 hours.

(6) Please do not insert or pull out the charger plug with wet hands to prevent electric shock.
