MTB01, MTB02 Digital Multimeter Item Ref: 600.101UK, 600.102UK WARNING Please read this manual thoroughly and ensure all contents are fully understood before use of the apparatus. Warning To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere 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. Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and grounding. The rotary switch should be placed in the right position and no changeover of range shall be made during measurement being conducted to prevent damage of the Meter. When the meter working at an effective voltage over 60V in DC or 30Vrms in AC, special care should be taken for there is danger of electric shock. Use the proper terminals, function, and range for your measurements. 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. When using the test leads, keep your fingers 600.101/102UK User Manual behind the finger guards. Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes or hFE. Replace the battery as soon as the battery indicator appears. With a low battery, the meter may produce false readings that can lead to electric shock and personal injury. Remove the connection between the testing leads and the circuit being tested and turn the meter power off before opening the meter case. 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 in regular basis. No abrasive and solvent should be used to prevent the surface of the meter from corrosion, damage and accident. The meter is suitable for indoor use only. Turn the meter power off when it is not in use and take out the battery when not using for a long time. Check the battery at regular basis as it may leak when it has been using for some time, replace the battery as soon as leaking appears. A leaking battery will damage the meter. 600.101/102UK User Manual General Specifications Max display: LCD 3 ½ digits (1999 count) 0.5" high Polarity: Automatic, indicated minus, assumed plus.

Set RANGE switch to desired VOLTAGE position, if the voltage to be measured is not known beforehand, set switch to the highest range and reduce it until satisfactory reading is obtained. 3. Connect test leads to device or circuit being measured. 4. Turn on power of the device or circuit being measured voltage value will appear on Digital Display along with the voltage polarity. DC CURRENT MEASUREMENT 1. Red lead to "VmA". Black lead to "COM" (for measurements between 200mA and 5A connect red lead to "5A" jack with fully depressed.) 2. Set RANGE switch to desired DCA position. 3. Open the circuit to be measured, and connect test leads in SERIES with the load in with current is to measure. 4. Read current value on Digital Display. 5. Additionally, "5A" function is designed for intermittent use only. Maximum contact time of the test leads with the circuit is 10 seconds, with a minimum intermission time of 15 minutes between tests. RESISTANCE MEASUREMENT 1. Red lead to "VmA".
