SAFETY NOTES
Do not exceed the maximum allowable input range of any function.
When the instrument is not in use, press the ON/OFF key to turn off the meter.
Remove the battery if meter is to be stored for longer than 60 days.
CAUTIONS
Improper use of this meter can cause damage, shock, injury or death.
Read and understand this user manual before operating the meter.
Always remove the test leads before replacing the battery.
The meter itself for any damage before operating the meter. Repair or replace any damage before use.
Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard.
Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not “live”.
