SAFETY

1.1. personal precautions
When using this multimeter, please observe all normal safety rules concerning:
Protection against the dangers of electrical current.
Protection of the meter against misuse.
full compliance with safety standards can only be guaranteed if used with the test leads supplied. if necessary, they must be replaced with genuine sealey leads with the same electrical ratings. failure to do so will invalidate the warranty.
do not use leads if damaged or if the wires are bared in any way.
1 .2. general safetY instructions
familiarise yourself with the application and limitations of the multimeter as well as the potential hazards.
if in and do But consult a Qualified electrician.
▲ use extreme caution when working with high voltages.
When the meter is connected to a circuit, do not touch unused meter terminals.
When the magnitude of the value to be measured is unknown, set the range selector to the highest value available.
Before commencing testing, follow instructions below and select the correct input sockets, function and range on the multimeter.
Before rotating the rotary switch to change functions, disconnect the test leads from the circuit under test.
take care when working with voltages above 35V dc or 25V Ac rms. these voltages are considered a shock hazard. Keep fingers behind the probe barriers whilst measuring.
do not test voltages above 600V – the circuitry of the multimeter may be destroyed.
‰ Warning! never connect the multimeter to a voltage source / live circuit when the rotary switch is set to any other function apart from Voltage testing.
‰ Warning! never perform resistance, transistor, diode or continuity measurements on live circuits.
ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests.
‰ Warnning! 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”.
do not use the multimeter in a potentially explosive atmosphere.
never operate the meter unless the back cover and the battery and fuse doors are in place and fastened securely.
if any abnormal readings are observed, the multimeter must be checked out by an authorised technician.
When not in use, store the multimeter carefully in a safe, dry, childproof location out of direct sunlight.
storage temperature range -20°c to 60°c.
always turn off the power and disconnect the test leads before opening the doors to replace the fuse or batteries.
the user shall ensure that test probes are correctly selected in order to prevent danger. Probes shall be selected to ensure that adequate barriers guard against inadvertent hand contact with live conductors under test and that probes have minimal exposed probe tips. Where there is a risk of the probe tip short circuiting with other live conductors under test, it is recommended that the exposed tip length shall not exceed 4mm.
‰ Warning! never apply voltage or current to the meter that exceeds the specified maximum as shown below:

▲ Warning! use Extreme caution when working with high voltages.
Note: the warnings, cautions and instructions referred to in this manual cannot cover all possible conditions and situations that may occur. it must be understood that common sense and caution are factors which cannot be built into this product, but must be applied by the operator.
1.3. Battery installation (fig.1)
‰ Warning! to avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover.
1.3.1. disconnect the test leads from the meter.
1.3.2. open the battery cover by loosening the cover screw using a cross-head screwdriver.
1.3.3. insert the battery into battery holder, observing the correct polarity.
1.3.4. replace the battery cover. secure with the screw.
‰ Warning! to avoid electric shock, do not operate the meter until the battery cover is in place and fastened securely.
Note! if the meter does not work properly, check the battery to make sure that it is still charged and that it is properly inserted.

Operation

Notice: read and understand all warning and precaution statements listed in the safety section of this operation manual prior to using this meter. set the function select switch to the off position when the meter is not in use.
4.1. AC CURRENT MEASUREMENTS (fig.4)
‰ Warning! ensure that the test leads are disconnected from the meter before making current clamp measurements.
4.1.1. set the function switch to the 400.0A ~ 2.000A range.
4.1.2. If the range of the measured is not known, select the higher range first then move to the lower range if necessary.
4.1.3. Press the trigger to open jaw. fully enclose one conductor to be measured. the clamp meter lcd will display the reading.
4.2. Dc / Ac voltage measurement
4.2.1. insert the black test lead into the negative com terminal and the red test lead into the positive V terminal.
4.2.2. set the function switch to the V position.
4.2.3. select Ac or dc with the mode button.
4.2.4. connect the test leads in parallel to the circuit under test.
4.2.5. read the voltage measurement on the lcd display.
4.3. resistance measurement
4.3.1. insert the black test lead into the negative com terminal and the red test lead into the positive terminal.

4.3.2. Set the function switch to the position.
4.3.3. touch the test probe tips across the circuit or component under test. it is best to disconnect one side of the device under test so the rest of the circuit will not interfere with the resistance reading.
4.3.4. for resistance tests, read the resistance on the lcd display.
4.4. diode and continuity measurements (fig.5)
4.4.1. insert the black test lead banana plug into the negative com jack and the red test lead banana plug into the positive diode jack.
4.4.2. Turn the rotary switch to the position.
4.4.3. Press the mode button until “ “ appears in the display.
4.4.4. touch the test probes to the diode under test. forward voltage will indicate 0.4V to 0.7V. reverse voltage will indicate “ol”. shorted devices will indicate near 0mV and an open device will indicate “ol” in both polarities.

4.4.5. For Continuity Tests if resistance is <150Ω a tone will sound.
4.5. non contact ac voltage measurements
‰ Warning! risk of electrocution. Before use, always test the Voltage detector on a known live circuit to verify proper operation
4.5.1. touch the probe tip (fig. 2 item 14) to the live conductor or insert into the live side of the electrical outlet.
4.5.2. if Ac voltage is present, the detector light will illuminate.
note! the conductors in electrical cord sets are often twisted. for best results, rub the probe tip along a length of the cord to assure placing the tip in close proximity to the live conductor. note! the detector is designed with high sensitivity. static electricity or other sources of energy may randomly trip the sensor. this is normal operation.
4.6. MODE BUTTON (fig.2 item 8)
To select dc/Ac Volts, oHm / diode / continuity
4.7. DATA HOLD BUTTON(fig.2 item 5)
To freeze the lcd meter reading, press the data hold button. the data hold button is located on the left side of the meter (top button). While data hold is active, the Hold display icon appears on the lcd. Press the data hold button again to return to normal operation.
4.8. MAX HOLD BUTTON (fig.2 item 10)
The max. Hold position is used to measure the maximum value. the maximum measured value is updated continuously. Pressing once again, the button will release the hold and allow a further measurement.
4.9. RANGE BUTTON (fig.2 item 9)
When the meter is first turned on, it automatically goes into Auto Ranging. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. for measurement situations requiring that a range be manually selected, perform the following:
4.9.1. Press the RANGE button. The “Auto Range” display indicator will turn off, The “Manual Range” display indicator will turn on.
4.9.2. Press the range button to step through the available ranges until you select the range you want.
4.9.3. Press and hold the range button for 2 seconds to exit the manual ranging mode and return to Auto ranging.
