This Operating Manual covers information on safety and 

cautions. Please read the relevant information carefully and 

observe all the Warnings and Notes strictly.

Open the package case and take out the Meter. Check the 

following items carefully to check if there is any missing or 

damaged part:

This Meter complies with standards EN61010: in pollution 

degree 2, overvoltage category (CATIII 300V) and double 

insulation. CATIII: Distribution level, fixed installation, with 

smaller transient over voltages than CAT IV. Use the Meter 

only as specified in this operating manual. Otherwise, the 

protection provided by the Meter may be impaired. 

In this manual, a Warning indicates conditions and actions 

that pose hazards to the user, or may damage the Meter or 

the equipment under test. 

A Note indicates the information to which the user should 

pay attention on.

To avoid possible electric shock or personal injury, and to 

avoid possible damage to the Meter or to the equipment 

under test, adhere to the following rules:

In the event that there is any missing or damage, please 

contact your dealer immediately.

Before using the Meter, inspect the case. Do not use the 

Meter if it is damaged or the case (or part of the case) is 

removed. Look for cracks or missing plastic. Pay attention 

to the insulation around the connectors.

Inspect the test leads for damaged insulation or exposed 

metal parts. Check the test leads for continuity. Replace 

the damaged test leads with identical model number or 

electrical specifications before using the Meter.

When using the test leads, keep your fingers behind the 

finger guards.

Do not apply more than the rated voltage, as marked 

on the Meter, between the terminals or between any 

terminal and grounding.

When the Meter is working at an effective voltage over 

60V DC or 30V AC, special care should be taken because 

there is a danger of electric shock.

Use the proper function and range for your 

measurements.

Disconnect the circuit power and discharge all high 

voltage capacitors before testing current, resistance, 

diodes or continuity.

Replace the battery as soon as the battery indicator 

appears. With a low battery, the Meter might take false 

readings that can lead to an electric shock and personal 

injury.

When servicing the Meter, use only the same model or 

identical electrical specifications replacement parts.

The internal circuit of the Meter shall not be altered at will, 

in order to avoid damage of the Meter and any accident.

Soft cloth and mild detergent should be used to clean 

the surface of the Meter when servicing. No abrasives 

and solvents should be used to prevent the surface of the 

Meter from corrosion, damage and accident.

Do not use or store the Meter in an a humid, hot, 

explosive, inflammable place or with a strong magnetic 

field. The performance of the Meter may be deteriorated 

after being dampened.

Press 

SELECT

 to switch between resistance, AC/DC voltage, 

continuity buzzer and diode measurement modes. Press 

and hold the button for more than 2 seconds to enter in or 

exit “sleep” mode.

1. SELECT

To preserve battery life, the Meter automatically enters the 

“sleep” mode if you do not press any button for around 

10 minutes. The Meter can be activated by pressing any 

button, then it returns to the display of the function selected 

previously.

5. AUTO POWER OFF

To avoid electric shock or personal injury, read the “Safety 

Information” and “Rules for Safe Operation” carefully before 

using the Meter.

The Model JT2007 Pen Type (hereafter referred as “the 

Meter”) are 3,000 counts. The Meter uses a large scale of 

integrated circuits with professional multimeter IC as its 

core, and has a full range overload protection.

The Meter measures or tests the following:

Press 

HOLD

 to enter or exit hold mode (except in the auto 

scan mode). Press and hold the 

HOLD

 button for more than 

2 seconds, the meter will automatically holds the value 

which is obtained 6 seconds later. At this time,      is displayed 

and starts flashing. 

If it enters in the “sleep” mode while it is in the hold mode, 

the meter will still be in the hold mode when it is turned on.

2. HOLD

The MAX/MIN mode stores the minimum (MIN) and 

maximum (MAX) input values (except in the auto scan 

mode). Manual ranging occurs when you select this 

function. 

Press 

MAX/MIN

 button MAX         MIN         MAX/MIN and vice 

versa. 

In the hold mode and max/min mode, you should exit the 

hold mode first, then press and hold MAX/MIN for more 

than 1 second to exit the max/min mode.

Display Backlight and test lead light button. Press the 

button once to turn the display backlight and the test lead 

light on and press again to turn the display backlight and 

test lead light off. It will be automatically turned off after

Measurement Operation

The buzzer sounds every time the button is effectively 

pressed. When the meter will auto power off in 20 seconds, 

the buzzer beeps three times. Before powering off, there will 

be a long time buzzer beeps.

Before measurement, turn anticlockwise the blue cover and 

rock the input terminal. 

When all the measurement has been completed, turn 

clockwise the blue cover and then hide the input terminal 

(see figure 3).
