OPERATING INSTRUCTIONS

Warning

To avoid electric shock or damage to the instrument, do not attempt to measure voltages that may exceed 500 volts.
Check all parts of the instrument (e.g. wires, connectors, etc.) individually before using the instrument.

DC voltage measurement

Connect the red end of the wire to the "V Ω mA" compartment, the black end to the "COM" compartment.
Set the switch at the desired DCV position; if the voltage to be measured is not known in advance, set the switch to the highest limit and lower it until the instrument reads satisfactorily.
Connect wires to the mechanism, instrument, or circuit to be measured.
Turn on the instrument and the voltage magnitude/value will appear on the electronic display along with the voltage polarity.

AC voltage measurement

Red wire "V Ω mA", black with "COM" (for measurements between 220 mA and 10 A, connect the red wire to the 10 A branch).
Set the switch to the selected DCA position.
Open the circuit to be measured and connect the wires in series with the load inside.
Read the current reading on the display.

Transistor hFE measurement

Set the switch to the hFE position.
Determine if the transistor is of the PNP or NPN type and whether it accommodates the emitter, base, and connecting wires. Insert the wires into the correct holes of the hFE cartridge on the front panel.
The meter will show the approximate hFE value provided the base current is 10 mA and Vce2.8V.

Temperature measurement

Connect a K-type thermoelectric element to the "V Ω mA" and "COM" compartments.
Set the switch to the "TEMP" position

Room Temperature Measurement

The M-835 can be used to measure room temperature (0°C to 35°C) without a thermoelectric element. Simply set the switch to the RT position and the current room temperature will appear on the display.

Capacitive resistance measurement

Set the function switch to the F position to be used.
Connect the capacitor under test to the "V Ω mAÑx" compartment and "COM".

Sound test

Connect the red end of the probe to the "V Ω mA" and the black end to the "COM" compartment
Set the disk switch to the "sound" position.
Connect the wires to the two points of the circuit to be measured. If the resistance is below 100Ω, a beep will sound.

Frequency measurement

Set the switch to the "|_|¬" position
The signal to be tested (50 Hz for M-835...) will appear between "V Ω mA" and "COM" separators, the voltage power is approximately 5V p-p with 50Kohm of total resistance.

Replacing the battery and fuse

The fuse does not often need to be replaced, and is usually blown by user error. If the battery symbol appears on the screen, the battery must be replaced. To replace the battery or fuse (200 mA/250V), unscrew the two screws at the base of the instrument, then simply replace the old battery with a new one. Be careful not to confuse the polarity.
