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 or fuses.

Inspect the condition of the test leads and the meter itself for any damage before operating

the meter. Repair or replace any damage 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.

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".

If the equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.

This device is not a toy and must not reach children’s hands. It contains hazardous objects

as well as small parts that children could swallow. In case a child swallows any of the parts,

please contact a physician immediately

Do not leave batteries and packing material unattended; they can be dangerous for children.

In case the device is going to be unused for an extended period of time, remove the

batteries to prevent them from draining.

Expired or damaged batteries can cause cauterization on contact with skin. Always use

suitable hand protection.

See that the batteries are not short-circuited. Do not put batteries into fire.

OVERVOLTAGE CATEGORY III

This meter meets the IEC 61010-1 (EN 61010-1), 2010, 3rd edition standard for OVERVOLTAGE

CATEGORY III. Cat III meters are protected against overvoltage transients in fixed installation at the

distribution level. Examples include switches in the fixed installation and some equipment for

industrial use with permanent connection to the fixed installation.

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 Protection Limits

Function Maximum Input

V DC or V AC 600V DC and AC, 200Vrms on 400mV range

mA AC/DC 500mA 600V fast acting fuse

A AC/DC 10A 600V fast acting fuse (30 seconds max every 15

minutes)

Frequency, Resistance, Capacitance,

Duty Cycle, 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. NEVER connect the meter leads across a voltage source while the function switch is in the

current, resistance, or diode mode. Doing so can damage the meter.

5. ALWAYS discharge filter capacitors in power supplies and disconnect the power when making

resistance or diode tests.

6. ALWAYS turn off the power and disconnect the test leads before opening the covers to replace

the fuse or battery.

7. NEVER operate the meter unless the back cover and the battery and fuse covers are in place

and fastened securely.

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 “OL” 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 green V position.

2. Press the SELECT button to indicate “DC” on the display.

3. Insert the black test lead banana plug into the negative COM jack.

Insert the red test lead banana plug into the positive Vjack.

4. 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.

5. Read the voltage in the display.

AC VOLTAGE MEASUREMENTS

WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts

inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As

a result, the reading may show 0 volts when the outlet actually has voltage on it. Make sure the

probe tips are touching the metal contacts inside the outlet before assuming that no voltage is

present.

CAUTION: Do not measure AC 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 green Vposition.

2. Press the SELECT button to indicate “AC” on the display.

3. Insert the black test lead banana plug into the negative COM jack.

Insert red test lead banana plug into the positive Vjack.

4. Touch the black test probe tip to the neutral side of the circuit.

Touch the red test probe tip to the “hot” side of the circuit.

5. Read the voltage in the display.

CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds.

Exceeding 30 seconds may cause damage to the meter and/or the test leads.

1. Insert the black test lead banana plug into the negative COM jack.

2. For current measurements up to 4000µA DC, set the function switch to

the yellow µA position and insert the red test lead banana plug into the

µA/mA jack

3. For current measurements up to 400mA DC, set the function switch to

the yellow mA position and insert the red test lead banana plug into the

µA/mA jack.

4. For current measurements up to 10A DC, set the function switch to the

yellow 10A range and insert the red test lead banana plug into the 10A

jack.

5. Press the SELECT button to indicate “DC” on the display.

6. Remove power from the circuit under test, then open up the circuit at the

point where you wish to measure current.

7. 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.

8. Apply power to the circuit.

9. Read the current in the display.
