RH70%Product Usage: 1. Used to verify the accuracy and linearity of handheld 3 1/2 digital multimeters. 2. Used to verify the accuracy and linearity of handheld 4 1/2 digital multimeters, must keep the same temperature and humidity as the data sheet specified.
Caution: 1. The pull switch can only keep one ON each time, no two ON allowed at the same working time. 2. If U like to verify the accuracy and linearity of handheld 4 1/2 digital multimeters, try to keep the same temperature and humidity as the data sheet specified. 3. Try to verify in a low air flow environment, try to avoid direct cold wind from the air conditioner as it may cause some additional errors.
