TRUPER MUT-830 Digital Multimeter

WARNING
To prevent probable electric shock or personal injury, damage to the Digital multimeter or equipment being tested, the following rules must be followed:

• Before using the Digital multimeter inspect the case. Do not use the Digital multimeter if damaged (or part of the case) has been removed. Look for cracks or missing plastic Double check insulation around the testing probes.
• 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 must be placed in the correct position and there must be no changes while the measurement is being carried out.
• Special care should be taken when the Digital multimeter is working at an effective voltage higher than 60 V in DC or 30 V RMS AC, as there is a danger of electric shock.
• Use the appropriate terminals, functions and range for the measurements. Do not use or store the Digital multimeter in high temperature, humid environments and strong magnetic fields are present. The performance of the Digital multimeter may deteriorate after it gets wet.
• When using test probes keep fingers behind the fingers guard.
• Disconnect the feeding circuit and discharge all the 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 Digital multimeter might produce false readings that can lead to electric shock and personal injury.
• Remove the connection between the test probes 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 spare parts with the same model number or identical electrical specifications.
• The internal circuit of the Digital multimeter shall not be altered at will to avoid damage to the Digital multimeter and any accident.
• Soft cloth and mild detergent should be used to clean the surface or 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 used for a long time. Replace the battery immediately if leaking appears. A leaking battery will damage the Digital multimeter.

OPERATING INSTRUCTIONS

D.C. AND A.C. MEASURING

1. Connect the red test probe to the “V ΩmA” connector, the BLACK test probe to the “COM” connector
2. Turn the RANGE switch to the desired voltage position. If the voltage to be measured is not known in advance, set the switch to the highest range and reduce to the desired reading.
3. Connect the test probes to the device or circuit to be measured.
4. Turn on the device or circuit to be measured. The value of the voltage will appear on the digital display along with the polarity of the voltage.

DIRECT CURRENT MEASUREMENT

1. The red tip in “V ΩmA”. The black tip is set to “COM” (for measurements between 200 mA and 10 A, connect the red tip to the “10 A” tip by pressing it down fully).
2. The RANGE switch in the desired DCA range.
3. Open the circuit to be measured and connect the test probes IN SERIES with the load in the current to be measured.
4. Read the current value on the digital display.
5. An additional “10 A” function is designed for intermittent use only. The maximum contact time with the circuit is 15 seconds with a minimum intermediate time of seconds between tests.

RESISTANCE MEASUREMENT

1. The red tip in “V ΩmA”. The black tip to “COM”.
2. The RANGE switch to the desired OHM position.
3. If the resistance to be measured is connected to a circuit, turn off the power and discharge all capacitors before making the measurement.
4. Connect the test probes to the circuit to be measured.
5. Read the resistance value on the digital display.

DIODE MEASUREMENT

1. The red test probe to “V ΩmA”, the black test probe to “COM”.
2. The RANGE switch is in position “ “.
3. Connect the red test probe to the anode of the diode to be measured and the black test probe to the cathode.
4. The voltage drop in mV will be shown. If the diode reverses, the number “1” is displayed.

hFE TRANSISTOR MEASUREMENT

1. Set the RANGE switch to the hFE range.
2. Determine if the transistor is the PNP type of NPN and locate the tips of the emitter, base, and collector. Insert the tips into the correct holes in the hFE plug on the adapter.
3. The Digital multimeter will display the approximate hFE value in the base current condition of 10 mA and Vce 2.8 V.

AUDIBLE CONTINUITY TEST

2. The test probe to “V ΩmA”, the black test probe to “COM”
3. Connect the probe to the Battery

BACKLIT DISPLAY FUNCTION
This Digital multimeter has a backlit display function. Press the LIGHT button to send the backlight LED

BATTERY AND FUSE REPLACEMENT
The fuse almost never needs to be replaced and almost always blows at operator error. If “ ” appears on the display, it indicates that the battery needs to be  replaced. To replace the battery and the fuse (F500 mA / 250 V), remove the two screws on the housing’s bottom. Remove the used batteries and fuses and replace with new ones. Be careful to maintain the polarity.
