SAFETY INSTRUCTIONS
This meter has been designed for safe use, but must be operated
with caution. The rules listed below must be carefully followed for
safe operation.
1. NEVER apply voltage or current to the meter that exceeds the
specified maximum:
Input Limits
Function Maximum
Input
V DC, VAC, Frequency, Duty Cycle 600V DC/AC
AAC, ADC 400A DC / AC
Resistance , Diode test , Continuity 250V DC/AC
Capacitance
Temperature(°F/'C ) 250V DC/AC
2. USE EXTREME CAUTION when working with high voltages
3. DO NOT measure voltage if the voltage on the "COM" input
jack exceeds 240V above earth ground
4. DONOT measure current of circuits whose voltage is greater
than 240V above earth ground
5. NEVER connect the meter leads across a voltage source
while the function switch is in the resistance or diode mode.
Doing so can damage the meter
6. ALWAYS turn off the power and disconnect the test leads
before opening the doors to replace the fuse or batteries
7. NEVER operate the meter unless the back cover is in place
and fastened securely

SAFETY SYMBOLS
This symbol adjacent to another symbol,
terminal or operating device indicates that the
operator must refer to an explanation in the
Operating Instructions to avoid personal injury
or damage to the meter
This WARNING symbol indicates a potentially
hazardous situation, which if not avoided, could
result in death or serious injury
This CAUTION symbol indicates a potentially
hazardous situation, which if not avoided, may
result in damage to the meter
This symbol advises the user that the
terminal(s) so marked must not be connected to
a circuit point at which the voltage, with respect
to earth ground, exceeds (in this case) 600
VAC or VDC
This symbol adjacent to one or more terminals
identifies them as being associated with ranges
that may, in normal use, be subjected to
particularly hazardous voltages. For maximum
safety, the meter and its test leads should not
be handled when these terminals are energized
This symbol indicates that a device is protected
throughout by double insulation or reinforced
insulation
