Data Hold Function; Dc Zero; Inrush Function - Sonel CMP-1006 Manual De Uso

 Turn the function switch to 
button to select the diode function if necessary (diode symbol
will appear on the LCD when in Diode test mode),

Touch the test probe tips to the diode or semiconductor junc-
tion under test. Note the meter reading,

Reverse the test lead polarity by reversing the red and black
leads. Note this reading,

The diode or junction can be evaluated as follows:
 If one reading displays a value (typically 0.400V to 0.900V)
and the other reading displays OL, the diode is good;
 If both readings display OL the device is open;
 If both readings are very small or '0', the device is shorted.


Press the DC ZERO button to zero the display. "ZERO" will
appear in the display. The displayed reading is now the actual
value less the stored "zero" value;

Inrush Function

The Inrush current function for AC current measurement to de-
tect the starting-up current of a motor. In ACA modes, press
INRUSH button will force meter to enter INRUSH mode. Then LCD
Displays "- - - -" until the motor starting up an being detected. The
detection will be done only one time and the output reading will be
hold. To exit INRUSH mode, press INRUSH button more than one
