WARNING: USE EXTREME CAUTION IN THE USE OF THIS
DEVICE. Improper use of this device can result in injury or

death. Follow all safeguards suggested in this manual in addition
to the normal safety precautions used in working with electrical
circuits. DO NOT service this device if you are not qualified to do
so.

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 or V AC 1000VDC/AC rms
mA AC/DC 400mA AC/DC
A AC/DC 10A AC/DC (20A for 30 seconds

max every 15 minutes)

Resistance, Diode Test,

1000VDC/AC rms
Continuity, Capacitance,
Frequency, Temperature

2. USE EXTREME CAUTION when working with high voltages

3. DO NOT measure voltage if the voltage on the "COM" input

jack exceeds 1000V above earth ground

4. DO NOT measure current of circuits whose voltage is greater

than 600V 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 cover to replace the fuse or battery

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.

WARNING

CAUTION

MAX
1000V

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 damage to the product.

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)
1000 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.
