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 600V DC/AC, 200Vrms on 200mV

range

mA AC/DC 200mA 250V fast acting fuse

A AC/DC 20A 250V fast acting fuse(30

seconds max every 15 minutes)

Resistance, Diode Test,

Continuity 250Vrms for 15sec max

Temperature 60V DC/24V AC

2. USE EXTREME CAUTION when working with high voltages

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

jack exceeds 600V 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 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.

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)

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.

BATTERY INSTALLATION

WARNING: To avoid electric shock, disconnect the test leads

from any source of voltage before removing the battery cover.

1. Disconnect the test leads from the meter.

2. Remove the rear battery cover by removing the two screws

using a Phillips head screwdriver.

3. Insert the battery into battery clips, observing the correct

polarity.

4. Put the battery cover back in place and secure with the two

screws.

WARNING: To avoid electric shock, do not operate the meter

until the battery cover is in place and fastened securely.

NOTE: If your meter does not work properly, check the fuses and

battery to make sure that they are still good and that they are

properly inserted.

OPERATING INSTRUCTIONS

WARNING: Risk of electrocution. High-voltage circuits, both AC

and DC, are very dangerous and should be measured with great

care.

1. ALWAYS turn the function switch to the OFF position when the

meter is not in use.

2. If “1 ” appears in the display during a measurement, the value

exceeds the range you have selected. Change to a higher range.

NOTE: On some low AC and DC voltage ranges, with the test

leads not connected to a device, the display may show a random,

changing reading. This is normal and is caused by the high-input

sensitivity. The reading will stabilize and give a proper

measurement when connected to a circuit.

DC VOLTAGE MEASUREMENTS

CAUTION: Do not measure DC voltages if a motor on the

circuit is being switched ON or OFF. Large voltage surges may

occur that can damage the meter.

1. Set the function switch to the

highest V DC position.

2. Insert the black test lead banana

plug into the negative (COM) jack.

Insert the red test lead banana

plug into the positive (V) jack.

3. Touch the black test probe tip to

the negative side of the circuit.

Touch the red test probe tip to the

positive side of the circuit.

4. Read the voltage in the display.

Reset the function switch to

successively lower V DC positions

to obtain a higher resolution

reading. If the polarity is reversed,

the display will show (-) minus

before the value.
