• Please use the meter according to the measurement category, voltage or current rating specified in the meter or manual.
• Please observe local and national safety regulations. Wear personal protective equipment (such as approved rubber gloves, masks and flame retardant clothing, etc.) to prevent injury caused by electric shock and electric arc when dangerous live conductors are exposed.
• When the " " symbol is displayed on the meter, please charge battery in time to prevent measurement error.
• Do not use the meter in the environment with explosive gas or steam or humid environment.
• When using the probe, please hold your fingers behind the probe finger guard.
• When measuring, please connect the null or ground wire first, then the live wire; when disconnected, please disconnect the live wire first, and then the null or ground wire.
• Remove the probe from the meter before opening the case or battery cover. Do not use the meter when the meter is disassembled or the battery cover is opened.
• The meter can only be used together with the probe provided to meet the requirements of the safety standard. If the probe is damaged and needs to be replaced, the probe of the same model and electrical specification must be replaced.
