a. Safety guard.

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)
