Q: Why it cannot power on?
A: Battery is flat, Connect to a charger to recharge, Poor battery contact, Check battery installation (if necessary).
Q: Why the Inaccurate temperature reading?
A: Incorrect emissivity setting, Adjust the emissivity according to the material being measured, Not sufficiently preheated, Preheat for 20 minutes after switching on, Affected by ambient reflection, Set the reflection temperature compensation.
Q: Why the Short battery life?
A: Low-temperature environment, Low temperatures reduce battery life, Battery ageing, Contact after-sales service to replace the battery.
