TRUPER MUT-36 Digital Multimeter Instruction Manual

WARNING

To avoid possible electric shock or personal injury, and to avoid possible damage to the Digital multimeter or to the equipment under test, adhere to the following rules

• Before using the Digital multimeter inspect the case. Do not use the Digital multimeter 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 Digital  multimeter, between the terminals or between any terminal and grounding.
• The rotary switch should be placed in the right position and no any changeover of range shall be made during measurement is conducted to prevent damage of the Digital multimeter.
• When the Digital multimeter working at an effective voltage over 60 V in DC or 30 V RMS 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 Digital multimeter in an environment of high temperature, humidity, explosive, inflammable and strong magnetic field. The performance of the Digital multimeter may deteriorate after dampened.
• When using the test leads, keep your fingers behind the finger guards.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes.
• Replace the battery as soon as the battery indicator appears. With a low battery, the Digital multimeter might 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 Digital multimeter power off before opening the Digital multimeter case.
• When servicing the Digital multimeter, use only the same model number or identical electrical specifications replacement parts.
• The internal circuit of the Digital multimeter shall not be altered at will to avoid damage of the Digital multimeter and any accident.
• Soft cloth and mild detergent should be used to clean the surface of the Digital multimeter when servicing. No abrasive and solvent should be used to prevent the surface of the Digital multimeter from corrosion, damage and accident.
• The Digital multimeter is suitable for indoor use.
• Turn the Digital multimeter power off when it is not in use and take out the battery when not using for a long time. Constantly check the battery 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 Digital multimeter.

OPERATING INSTRUCTIONS

DC & AC VOLTAGE MEASUREMENT 

1. Connect red test lead to “INPUT” jack, Black lead to “COM” jack.
2. Set RANGE switch to desired VOLTAGE range, 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 & AC CURRENT MEASUREMENT 

1. Connect Red lead to “INPUT”. Black lead to “COM” (for measurements between 200 mA and 10 A connect red lead to “10 A” jack with fully depressed.)
2. Range switch to desired A range. The default function of the Digital multimeter is the measurement of DCA.
3. Press “select” button to switch to ACA measurement mode.
4. Open the circuit to be measured, and connect test leads in-series with the load in with current is to measure.
5. Read current value on the LCD.

RESISTANCE MEASUREMENT

1. Red lead to “INPUT”. Black lead to “COM”.
2. Range switch to desired Ω range.
3. If the resistance being measured is connected to a circuit, turn off power and discharge all capacitors before measurement.
4. Connect test leads to circuit being measured.
5. Read resistance value on Digital Display.

DIODE TEST

1. Connect Red lead to “INPUT”, Black lead to “COM”.
2. Set RANGE switch to “ ” range, and press “Select” button to select diode test function.
3. Connect the red test lead to the anode of the diode to be measured and black test lead to cathode.
