2. Safety

2-1. Safety Symbols

This symbol adjacent to another symbol, terminal or operang device

indicates that the operator must refer to an explanaon in the

operang instrucons to avoid personal injury or damage to the meter.

WARNING This WARNING

symbol indicates a potenally hazardous situaon, which if not

avoided, could result in death or serious injury.

CAUTION This CAUTION symbol indicates a potenally hazardous situaon, which if not

avoided, may result damage to the product.

MAX This symbol advises the user that the terminal(s) so marked must not be

connect 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 idenes them as being associat

with ranges that may, in normal use, be subjected to parcularly hazardous

voltages. For maximum safety, the meter and its test leads should not be handled

when these terminals are energized.

Please read this manual before switching the unit on.

earth ground.

4.Never connect the meter leads across a voltage source while the funcon switch

is in the current, resistance, or diode mode, doing so can damage the meter.

5.Always discharge lter capacitors in power supplies and disconnect the power

when making resistance or diode tests.

6.Always turn o the power and disconnect the test leads before opening the covers

to replace the fuse or baeries.

7.Never operate the meter unless the back cover and the baery and fuse covers are in

place and fastened securely.

selected using the rotary switch, navigate menus or control power to Meter circuits.

F1 Soware Key: Default switch to Graph measure.

F2 Soware Key: Default modes related to the rotary switch funcon

F3 Soware Key: Default into save mode default Display. And wake up for APO.

F4 Soware Key: Default modes MIN/MAX starts and stops MIN/MAX recording.

RANGE Buon: Into manual range and select range of the measure, if pressing the Range

Buon for greater that 1 second will return Auto Range.

HOLD/REL Buon: Freezes the present reading in the display and allows the

display to be saved,

if pressing the HOLD/REL Buon for greater that 1 second will switch relave mode.

HOLD/REL Buon: Freezes the present reading in the display and allows the display to be

saved,if pressing the HOLD/REL Buon for greater that 1 second will switch relave mode.

3-4.Understanding the Rotary Switch

• Select a primary measurement funcon by posioning the rotary switch to one of the

icons around its perimeter.

• For each funcon, the Meter presents a standard display for that funcon

(range, measurement units and modiers).

• Buon choices made in one funcon do not carry over into another funcon.

4.Measure Funcon

4-1.AC Voltage Measurement

WARNING: Risk of Electrocuon. The probe ps 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 ps 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 funcon switch to the VAC Posion.

2. Insert the black test lead into the COM Input Jack and the red test lead into the Posive

Input Jacks.

2. Remove the baery door assembly by using a standard blade screwdriver to turn

the baery door screw one-half turn counterclockwise.

3. Replace the baeries with 7.4 volt charge baeries Observe proper polarity.

4. Reinstall the baery door assembly and secure it by turning the screw one-half

turn clockwise.

8.Replacing the Fuses

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage

before removing the meter cover.

WARNING: To avoid electric shock, do not operate your meter unl the fuse cover is in place

and fastened securely.

Referring to Figure, examine or replace the Meter’s fuses as follows:

1. Turn the Meter o and remove the test leads from the terminals.

2. Remove the baery door assembly by using a standard blade screwdriver to turn

the baery door screw one-half turn counterclockwise.

3. Remove the fuse by gently prying one end loose, then sliding the fuse out of its bracket.

4. Install only specied replacement fuses.

5. Reinstall the baery door assembly and secure it by turning the screw one-half

turn clockwise.

6. Remove the six screws securing the rear cover.

7. Gently remove the old fuse and install the new fuse into the holder.

8. Replace and secure the rear cover, baery and baery cover.
