1. 

Insert  the  black  test  lead  banana  plug  into  the 
negative 

COM

  jack  and  the  red  test  lead  banana 

plug into the positive diode jack. 

2. 

Turn the rotary switch to the

•))) 

  position. 

3. 

Touch  the  test  probes  to  the  diode  under  test. 
Forward  voltage  will  indicate  400  to  700mV. 
Reverse  voltage  will  indicate  “

I

”.  Shorted  devices 

will  indicate  near  0mV.  Shorted  devices  will 
indicate  near  0mV  and  an  open  device  will 
indicate “

I

” in both polarities. 

 

TEMPERATURE MEASUREMENTS 

WARNING: 

To avoid electric shock, disconnect both test 

probes  from  any  source  of  voltage  before  making  a 
temperature measurement. 

1. If you wish to measure temperature in 

o

F, set the function 

switch  to  the 

o

F  range.  If  you  wish  to  measure 

temperature in 

o

C, set the function switch to the 

o

C range. 

2. Insert  the  type  K  thermocouple  probe  black  test  lead 

banana plug into the negative 

COM

 jack and the red test 

lead banana plug into the positive 

Temp

 jack.. 

3. Touch  the  Temperature  Probe  head  to  the  part  whose 

temperature  you  wish  to  measure.  Keep  the  probe 
touching  the  part  under  test  until  the  reading  stabilizes 
(about 30 seconds). 

4. Read  the  temperature  in  the  display.  The  digital  reading 

will indicate the proper decimal point and value. 

WARNING: 

To  avoid  electric  shock,  be  sure  the 

thermocouple  has  been  removed  before  changing  to 
another measurement function.
