200mVV & V~HzΩmA & mA~10A & 10A~Function Red Lead Connection Input LimitsProfessional tradesmanís multimeter with 25mm LCD display. Durable case with protective boot, probe storage andintegral two-position stand. Features heavy-duty circuitry with auto over-range display, auto zero, auto power-off, audiblecontinuity warning and polarity protection on all necessary ranges. Supplied with probe test leads and temperature probe.! WARNING! Ensure that you read, understand and apply the safety and operational instructions before connecting the multimeter. Only when you are surethat you understand the procedures is it safe to proceed with testing.Operating temperature range 0OC to 40OC.Remember to turn on multimeter before use and to turn it off when measurement is completed.NOTE: WHEN THE FIGURE ë1í IS DISPLAYED, IT INDICATES AN OVER-RANGE SITUATION AND A HIGHER RANGE NEEDS TO BE SELECTED.3.1. MEASURING VOLTAGE3.1.1. Connect the black test lead to the ëCOMí input socket and the red test lead to the ëV/Ωí input socket.3.1.2. Set the rotary switch to the required ëV ë (dc) or ëV ~ ë (ac) range and connect test leads across the source or load under measurement. The polarityof the red test lead connection will be indicated when measuring dc voltages.3.2. MEASURING CURRENT3.2.1. Connect the black test lead to the ëCOMí input socket and the red test lead to the ëmAí input socket for measuring a maximum of 200mA. For a maximumof 10A connect the red lead to the 10A socket.3.2.2. Set the rotary switch to the required ëA ë (dc) or ëA ~í (ac) range and connect test leads in series with the load under measurement. The polarity of thered lead connection will be indicated when measuring dc.3.3. MEASURING RESISTANCE3.3.1. Connect the black lead to the ëCOMí input socket and the red test lead to the the V/Ω input socket (the polarity of the red lead is ë+í).3.3.2. Set the rotary switch to the required ëΩí range and connect the test leads across the resistance under measurement.3.3.3. If the resistance being measured exceeds the maximum value of the range selected or the input is not connected, an over-range indication ë1í will be displayed.3.3.4. When checking in-circuit resistance, ensure that the circuit under test has all power removed and all capacitors have been fully discharged.3.3.5. When measuring resistance over 1MΩ, the meter may take a few seconds to get a stable reading. This is normal for high resistance measurements.3.3.6. In the 200MΩ range the display reading is approx. 1.0 when the test leads are shorted. This figure must be subtracted from measured results. For example,when measuring a 100MΩ resistance the display reading would be 101.0 and the corrected result would be 101.0 - 1.0 = 100MΩ.3.4. MEASURING CAPACITANCE3.4.1. Set the rotary switch to the required ëFí range.3.4.2. Before inserting capacitor into the capacitor socket, ensure that the capacitor has been fully discharged.1.1. PERSONAL PRECAUTIONS# When using this multimeter, please observe all normal safety rules concerning:Protection against the dangers of electronic 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 Sealeyleads with the same electronic ratings. Failure to do so will invalidate the warranty.$ DO NOT use leads if damaged or if the wire is 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 ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.# When the meter is connected to a circuit, do not touch unused meter terminals.# When the value scale to be measured is unknown beforehand, set the range selector to the highest value.# Before rotating the range selector to change functions, disconnect test leads from the circuit under test.! WARNING! Never perform resistance measurements on live circuits.# Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe barriers while measuring.# Before attempting to insert transistors for testing, ensure that test leads have been disconnected.# Components should not be connected to the transistor socket, capacitor socket or temperature socket when making voltage measurement with the test leads.# When not in use, store the multimeter carefully in a safe, dry, childproof location. Storage temperature range -10OC to 50OC.INSTRUCTIONS FOR:32 FUNCTION MULTIMETERMODEL: MM302.V2Thank you for purchasing a Sealey product.
