Diode And Continuity Test; Battery And Fuse Replacement - Velleman DVM811 User Manual

10.4 DIODE AND CONTINUITY TEST

Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
1. Set the rotary switch in the
2. For measuring the diode, connect the red test lead to the anode of the
diode to be tested and the black test lead to the cathode of the diode.
The approx. forward voltage drop of the diode will be displayed.
For measuring continuity, connect the test leads to two points of the
circuit to be tested. If continuity exists, the built-in buzzer will sound.
10.5 BATTERY TEST
1. Set the rotary switch in the 1.5V or 9V position.
2. Connect the test leads to the battery to be tested and read the LCD
display.

11. Battery and Fuse Replacement

WARNING: To avoid electrical shock always disconnect the test
leads prior to opening the housing. To prevent fire hazards, only use
fuses with the same ratings as specified in this manual.
Remark: refer to the warning on the battery compartment
There are no user-serviceable parts inside the device.
Refer to an authorized dealer for service and/or spare parts.
Disconnect the test leads from the test points and remove the test
leads from the measuring terminals before replacing the batteries or
fuses.
• When" " is displayed, the battery should be replaced.
• Fuses rarely need replacement and blown fuses almost always result
from human error.
To replace the battery:
• Switch of the meter.
• Remove the screw at the back of the case and gently open the housing.
• Remove the old battery and insert a new one.
• Close the housing and fasten the screw.
Battery: 1x CR2032, make sure to respect the polarity
Fuses: F0.5 A/500 V, 5 x 20 mm
Make sure the meter is closed tight and put the protective edge back in
place before using the meter.
