Durite 0-798-80 User manual

Pen Type Multi Meter
Part 0-798-80
Overview
This Operating Manual covers information on safety and cautions. Please read the relevant information carefully and observe all
the Warnings and Notes strictly.
Warning
To avoid electric shock or personal injury, read the "Safety Information" and "Rules for Safe Operation" carefully before using the
Meter.
The Model 0-798-80 (hereafter referred to as “the Meter”) are 3000 counts pen type digits millimetres. The Meter uses large scale
of integrated circuit with professional multi meter IC as its core and has full range overload protection.
The Meter measures or tests the following:
• AC/DC voltage
• Resistance
• Diode
• Continuity
• Capacitance
Safety Information
This Meter complies with standards EN61010: in pollution degree 2, over voltage 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 identifies conditions and actions that pose hazards to the user, or may damage the Meter or the equip-
ment under test. A Note identifies the information that user should pay attention on.
Warning
To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, ad-
here to the following rules:
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. Check the test leads for continuity. Replace 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 ground-
ing.
When the Meter is working at an effective voltage over 60V DC or 30V AC, special care should be taken for there is danger of elec-
tric shock.
Use the proper function, and range for your measurements.
Disconnect 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 produce false readings that can
lead to 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 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 abrasive and solvent should be
used to prevent the surface of the Meter from corrosion, damage and accident.
Do not use or store the Meter in an environment of high temperature, humidity, explosive, inflammable and strong magnetic
field. The performance of the Meter may deteriorate after dampened.

International Electrical Symbols Display Symbols
Button Function and Auto Power Off
SELECT
Press SELECT to switch between resistance, AC/DC voltage, continuity buzzer and diode measurement modes. Press and hold more than
2 seconds in or exit “sleep” mode.
HOLD
Press HOLD to enter and exit hold mode (except under auto scan mode).
Press and hold the HOLD button more than 2 seconds, the meter automatically holds the value which obtains at 6 seconds later, at this
time, His displayed and flickering.
If enter “sleep” mode under hold mode, the meter still in the hold mode when it is turned on.
MAX/MIN
The MAX/MIN mode stores minimum (MIN) and maximum (MAX) input values (except under auto scan mode). Manual ranging comes
when you select this function.
Press MAX/MIN button MAX to MIN to MAX/MIN and vice versa.
Under hold mode and max/min mode, should exit hold mode first then press and hold MAX/MIN more than 1 second to exit max/min
mode.
Display Backlight and test lead light button, Press once to turn the display backlight and test lead light on and press again to turn the dis-
play backlight and test lead light off. It will automatically turn off after around 1 minute.
AUTO POWER OFF
To preserve battery life, the Meter automatically goes into a “sleep” mode if you do not press any button for around 10 minutes. The
Meter can be activated by pressing any button, then returns to the display for the
function selected previously
BUZZER
The buzzer phonate with every time a button is effectively pressed. When the meter will auto auto turn off in 20 seconds the buzzer
beeps three times. Before power off there will be a long buzzer beep.

Measurment Operation
Before measurement, turn the red cover anticlockwise and rock the input terminal.
When all the measurement has been completed, turn the red cover then hide the input terminal.
Remark:
1. Under autoscan mode the max range is 300uF.
2. There is a residual reading when the circuit is
open. To measure a small value of capacitance,
subract it to ensure accuracy.

Maintenance
This section provides basic maintenance information and battery replacement instruction.
Warning
Do not attempt to repair or service your Meter unless you are qualified to do so and have the relevant calibration, performance test, and
service information. To avoid electrical shock or damage to the Meter, do not get water inside the case.
A. General Service
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. To clean the terminals with cotton
bar with detergent, as dirt or moisture in the terminals can affect readings.
Turn the Meter off when it is not use and take out the battery when not using for a long time. Do not store the Meter in a place of humid-
ity, high temperature, explosive, inflammable and strong magnetic field.
B. Replacing the Battery
Warning
To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indica-
tor appears. To replace the battery:
Turn the Meter off. Disconnect the connection between the testing leads and the circuit under test, and remove the testing leads away
from the input terminals of the Meter.
Remove the screw from battery compartment and separate the battery compartment from the case bottom.
Remove the battery from the battery compartment.
Replace the battery with a new 3V battery 5. Rejoin the case bottom and the battery compartment, and reinstall the screw.
