2.1 Safety Notes

• Do not exceed the maximum input range for any function (see table in Sec-
tion 2.3).
• Do not apply voltage to the meter when the resistance, capacitance, or di-

• Set the function switch OFF when the meter is not in use.

WARNING
CAUTION
• Improper use of this meter can cause damage, shock, injury or death. Read and under-
stand this user manual before operating the meter.
• Set the function switch to the appropriate position before measuring.
• When measuring voltage do not switch to the current or resistance modes.
• Do not measure current on a circuit whose voltage exceeds 600 V.
• When changing ranges, always disconnect the test leads from the circuit under test.
• Voltage checks on electrical outlets can be difficult and misleading because of the un-
certainty of connection to the recessed electrical contacts. Other means should be
used to ensure that the terminals are not 'live'.
• Do not place or use the device in strong direct sunlight for extended periods.
