  OPERATING INSTRUCTION
4. OPERATING INSTRUCTION 
4.1 MISCONNECTION ALARM 
The input jacks of the meter are equipped with sound and 
light alarms against misconnection of test leads. 
4.1.1 At V Ω Hz Duty   ranges: 
1 The red lights at the “IN” and “COM” jacks will be off 
after the test leads are plugged in. 
2 The buzzer will sound upon misconnection of the test 
leads in the “mA” or “10A” jacks to warn the user.    At 
the same time, the lights at the “IN” and “COM” jacks 
will flash to remind the user to plug in the test leads 
there. 
4.1.2 At µA mA, TEMP ranges  
1 The red lights at the “mA” and “COM” jacks will be off 
after the test leads are plugged in. 
2 The buzzer will sound upon misconnection of the test 
leads in the “IN” or “10A” jacks to warn the user.  At 
the same time, the red lights at the “mA” and “COM” 
jacks will flash to  remind the user to plug in the test 
leads there. 
4.1.3 At 10A range  
1) The red lights at the “10A” and “COM” jacks will be off 
after the test leads are plugged in. 
2) The buzzer will sound upon misconnection of the test 
leads in the “IN” or “mA” jacks to warn the user.
