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:

Maximum Input

VAC

600V DC/AC

V DC or V

600V DC/AC, 200Vrms on 200mV

mA DC

200mA 250V fast acting fuse

A DC 10A 250V fast acting fuse

(30 seconds max every 15 minutes)

Resistance

, Continuity

250Vrms for 15sec max

2. USE EXTREME CAUTION when working with high

voltages.

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

input jack exceeds 500V 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 doors to replace the fuse or

batteries.

7. NEVER operate the meter unless the back cover and the

battery and fuse doors are 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

MAX

WARNING

CAUTION

connected to a circuit point at which the

voltage with respect to earth ground

exceeds (in this case) 500 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 door.

1. Disconnect the test leads from the meter.

2. Open the battery door by loosening the screw using a

Phillips head screwdriver.

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

polarity.

4. Put the battery door back in place. Secure with the screw.

WARNING: To avoid electric shock, do not operate the

meter until the battery door is in place and fastened

securely.

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

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

they are properly inserted.

OPERATING INSTRUCTIONS

DATA HOLD BUTTON

The Data Hold function allows the meter to "freeze" a

measurement for later reference.

1. Press the DATA HOLD button to “freeze” the reading on

the indicator. The indicator “HOLD” will be appear in the

display.

2. Press the DATA HOLD button to return to normal

operation.

BACK LIGHT BUTTON

1. The BACK LIGHT button is used to turn the back light on

or off. Press the BACK LIGHT BUTTON to turn the back

light on.

2. Press the BACK LIGHT BUTTON to turn the back light

off.

WARNING: Risk of electrocution. High-voltage

circuits, both AC and DC, are very dangerous and

should be measured with great care.
