b. Jaw Trigger.
c. Rotary Range Selector.
d. LCD
e. COM Jack: it is used for the connection of negative signal
input while measuring DCV, ACV,Ω/ .
f. V/ΩJack: It is used for the connection of positive signal
input while measuring DCV,ACV,Ω/ .
g. RANGE Button: Manual ranging is allowed while the button
is pressed, and the symbol MANU is shown on LCD, The
auto ranging mode is activated again while pressing the
button more than 2 seconds or setting the range.
h. DATA HOLD button: The reading data shown on LCD can be
locked while pressing the button.
i. ZERO button: The reading data shown on LCD can
be reset to 0 while the button is pressed once, and
the symbol “ZERO” is also displayed on LCD, Press
the button again, the data cleared can be shown on
LCD, and the symbol “ZERO” begins to blink. To
abort the zero mode, hold down the button for more
than 1 second. (13E/13R)
