1.1. lnternational Safety Symbols
!
This symbol, adjacent to another symbol or terminal, indicates
the user must refer to the manual for further information.
This symbol, adjacent to a terminal, indicates that, under
normal use, hazardous voltages may be present.
Double insulation.
1.2. SAFETY NOTES
• Do not exceed the maximum allowable input range of any function.
• Do not apply voltage to meter when resistance function is selected.
• Set the function switch OFF when the meter is not in use.
1.3. WARNINGS
• Set function switch to the appropriate position before measuring.
• When measuring volts do not switch to current/resistance modes.
• When changing ranges using the selector switch always disconnect the
test leads from the circuit under test.
• Do not exceed the maximum rated input limits.
1.4. 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.
• Inspect the condition of the test leads and the meter itself for any
damage before operating the meter. Repair or replace if damaged 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.
• Remove the battery if the meter is to be stored for long periods.
• Always discharge capacitors and remove power from the device under
test before performing Diode, Resistance or Continuity tests.
• 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".
