To avoid electrical shock, remove test leads from measurement circuits before testing a transistor.
Connect red test lead to “V..mA”, black test lead to “COM”.
Set range switch to “ ” position.
Connect test leads to two points of circuit to be tested. If
continuity exists, built-in buzzer will sound.
BATTERY & FUSE REPLACEMENT
If “ ”appears on display, it indicates that the battery should be replaced.
Fuse rarely need replacement and blow almost always as a result of operator’s error.
fuse (200mA/250V) remove the 2 screws in the bottom of the case. Simply
remove the old, and replace with a new one.
Be careful to observe battery polarity.
Before attempting to open the case, always be sure that test leads have been disconnected from
measurement circuits. Close case and tighten screws completely before using the meter to avoid
Operator’s instruction manual
9 volt battery. NEDA 1604 6F22 006P type
Using this appliance in an environment with a strong radiated radio-frequency electromagnetic field
(approximately 3V/m), may influence its measuring accuracy. The measuring result can be strongly
deviating from the actual value.
If there is any cracking or break shown on the enclosure or cable please do stop use it.
Never use the meter to measure current if the circult to be measured might contain voltage
