4.3.2 Microwave Didoes
Most microwave didoes can not be tested by a DMM with a diode test
function. This is because the DMM does not supply enough power to
turn these diode on. We offer an accessory test lead, model TL60, that
boosts the power output so that microwave didoes can be adequately
tested. Consult your distributor for more details.
4.4 Measuring Current (Amps)
CAUTION!
THE CURRENT FUNCTIONS ARE PROT
E
CT
E
D BY A FUSE OF
600 VOLT RATING. TO AVOID DAMAGE TO THE INSTRUMENT,
CURRENT SOURCES HAVING OPEN CIRCUIT VOLTAGES
GREATER THAN 600 VOLTS DC OR AC MUST NOT BE
MEASURED.
NOTE: When taking current measurements, this Meter must be
connected in SERIES with the circuit (or circuit element)
under test. NEVER CONNECT THE TEST LEADS ACROSS
A VOLTAGE SOURCE while the rotary switch is set to
Amps. This can cause damage to the circuit under test or
this Meter.
• To measure current, you must break the circuit and connect the test
leads to two circuit connection points. The connection must be in
series with the current.
• In alternating current measurement, waveforms other than sine
wave causes error.
