WARRANTY This instrument is warranted to be free from defects in material and workmanship for a period of one year. Any instrument found defective within one year from the delivery date and returned to the factory with transportation charges prepaid, will be repaired, adjusted, or replaced at no charge to the original purchaser. This warranty does not cover expandable items such as batteries or fuses.
Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the meter serviced. + Do not operate the meter around explosive gas, vapor, or dust. * Do not apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground. Before use, verify the meter's operation by measuring a known voltage. When measuring current, turn off circuit power before connecting the meter in the circuit.
CAUTION To avoid possible damage to the meter or to the equipment under test, follow these guidelines: + Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance. * Use the proper terminals, function, and range for your measurements. + Before measuring current, check the meter's fuses and turn power OFF to the circuit before connecting the meter to the circuit.

1. FUNCTION AND RANGE WITH This switch is used to select the functions and desired ranges as well as to turn ON/OFF the meter. To extend the life of the battery, the switch should be in the "OFF" position when the meter is not in use. 2. DISPLAY 3 1/2 digit, LCD(12mm) 3. "COM" JACK Vulg in connector for black (negative) test lead. 4. "Velma" JACK Plug in connector for red (positive) test lead for all voltage, resistance and current { up to 200mA ) measurements. 5.

OPERATING INSTRUCTION DC CURRENT MEASUREMENT 1. Connect the red test lead to the "Velma" jack and the black test lead to the "COM" jack. 2. Set the range switch to the desired A= range. 3. Open the circuit in which the current is to be measured, and connect the test leads in series with the circuit. 4. Read the current value on the LCD display along with the polarity of the red test lead. DC VOLTAGE MEASUREMENT 1. Connect the red fest lead to the "Velma" jack and the black test lead to the "COM" jack. 2.
4. Connect the test leads across the resistor to be measured and read the resistance value on the LCD display. TEMPERATURE MEASUREMENT 1. Set the range switch to the "TEMP" range, and the meter will show the current room temperature without any external thermonuclear connections. 2. Connect the K type thermonuclear to the "Velma" and "COM" jacks. Contact the object to be measured with the thermonuclear carefully. Read the temperature value on the LCD display. TRANSISTOR TEST 1.
Cautions: a. This is output signal. be sure not to measure voltage b. There is no short circuit protection. ¢. The voltage of the reversed signal of the output terminal should not exceed 40Vp-p. BATTERY MEASUREMENT 1. Set the range switch to the desired “BAT” range {1.5V or 9V). 2. Connect the red test lead to the "Velma” jack and the black test lead to the "COM" jack. And connect the test leads to the two terminals of the battery to be measured and read the value on the LCD display.
