Arbitrary waveform generator
1. DC Voltage Measurement V- (DCV):
1.1 Connect RED test lead to “VΩmA” jack, BLOCK test lead to “COM” jack.
1.2 Set the FUNCTION switch to the desired V- (DCV) position. If not sure, set to the highest range.
1.3 Connect the test leads across the source or load under measurement.
2. DC Current Measurement A- (DCA):
2.1 Connect the RED test lead to “VΩmA” jack when the current is less than 200mA and to “10A” jack when the current is larger than 200mA. Connect the BLACK test lead to the “COM” jack.
2.2 Set the JUNCTION switch to the desired DCA position.
2.3 Connect the test leads across the source or load under measurement.
3. AC Voltage Measurement V~:
3.1 Connect the RED test lead to “VΩmA” jack and BLACK test lead to “COM” jack.
3.2 Set the FUNCTION switch to the desired ACV position.
3.3 Connect the test leads across the source or load under measurement.
4. Resistance Measurement (Ω):
4.1 Connect the RED test lead to “VΩmA” jack and BLACK test lead to “COM” jack.
4.2 Set the FUNCTION switch to the Ω position.
4.3 Connect the test leads across the resistor under measurement.
4.4 When measuring the resistance, the power should be turned off and in short circuit statues by connecting the two test leads.
5. Transistor hFE Measurement:
5.1 Set the FUNCTION switch to hFE position
5.2 Insert the E B C. of the PNP or NPN transistor to the proper jack in the socket on the front panel.
6. 50Hz Square Wave Output:
6.1 Connect RED test lead to the “VΩmA” jack and BLACK test lead to the “COM” jack.
6.2 Turn the FUNCTION switch to position and the RED and BLACK test leads being the output jack.
DC Power Supply:
1. Before applying power to your DC power supply, make sure that power select switch is correctly setting for you applicable AC power supply.
2. Connect the instrument to an AC power source using the power line core provided.
3.Do not connect a voltage that is greater than the current output voltage to the terminals of the instrument.
4.Never ground yourself when taking electrical measurements. Keep your body isolated from ground by using dry clothing; rubber shoes, rubber mat, or any approved insulating material.
5. Never touch exposed wiring, connections or any live circuit when attempting to take measurements.
6. Avoid shorting circuit the output of DC power supply.
7. Set the voltage and current adjustment knobs as you desire.
8. The unit should be stored in a dry and well ventilated place and the power cord removed if storing for long periods.
1. The meters can be safe only according to standard procedures when used in conjunctions with the supplied test leads. To replace damaged test leads with only the same model or same electric specifications.
2 To avoid risk of electric shock, do not use the meters before the cover is in place.
3 The range switch should be right position for the testing.
4 To avoid electric shock and damaging the instruments, the input signals are forbidden to exceed the specified limits.
5 When measuring TV set or switched power, attention should be paid to the possible pulses that may bring destruction to the circuit.
6 Range switch position is forbidden to be changed at random during measurement.
7 Take caution against shock in the course of measuring voltage higher than DC 60V & AC 30V.
8 Protection fuse should be replaced only with same type and same specification.
9 After operation is finished, set function switch at OFF to save battery power.
10 If the meter is without usage for long time, take out battery to avoid damage by battery leakage.
1. To Avoid Fire or Personal Injury
2. Use Proper Power Cord. Use only the power cord specified for this product and certified for the country of use.
3. Connect and Disconnect Properly. Do not connect or disconnect probes or test leads while they are connected to a voltage source.
4. Ground the Product. This product is grounded through the grounding conductor of the power cord. To avoid electric shock, the grounding conductor must be connected to earth ground. Before making connections to the input or output terminals of the product, ensure that the product is properly grounded.
5. Connect the Probe Properly. The probe ground lead is at ground potential. Do not connect the ground lead to an elevated voltage.
6. Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings and marking on the product. Consult the product manual for further ratings
information before making connections to the product.
7. Do Not Operate Without Covers. Do not operate this product with covers or panels removed.
8. Use Proper Fuse. Use only the fuse type and rating specified for this product.
9. Avoid Exposed Circuitry. Do not touch exposed connections and components when power is present.
