Cautions
•Do not usethe instrument around explosive gas, steam or inwet environment.
•The instrument shall be used in accordance with the specified measurement
category, voltage or current rating.
•Please be careful if the measurement exceeds 30V AC true RMS, 42V AC peak
or 60V DC. There may be danger of electric shock at this kind of voltage
•By measuring the known voltage to check whether the meter work is normal, if it
is not normal or damaged, do not use it again.
