Micronta 22-195A - CONTROL SWITCHES AND TERMINALS; Transistor Measurement Terminals; Meter Control Switches

6. hee terminal: Used for testing transistors
hee. Small type transistors can be plugged
directly into this terminal. Otherwise, use the
transistor test clip harness provided.
7. PNP-NPN switch: Press in for measuring
PNP transistors. Leave in the out position for
NPN transistors.
8. RANGE CONTROL switches:
a. MANUAL/AUTO — press in to cause the

range when in the manual range control
mode. When you reach the lowest range, this
switch has no effect.
9. BUZZER switch: Pressing in causes the
buzzer to sound when any function is activat-
ed (except PNP/NPN mode). Buzzer will also
sound when the input exceeds the maximum
range (except in kQ, CONT and Jœ check).
10. DATA HOLD switch: Holds the displayed
data on the LCD. "DH" will appear on the
LCD.
11. MEMORY switches:
a. MAX — press to display the highest value
recorded by the memory circuit.
b. MIN — press to display the lowest value
recorded by the memory circuit.
c. START/RESET — press in to activate the
memory function. "M" appears in the display.
Press again to release the memory function.
