FUNCTION BUTTONS

ON/OFF

To Power ON the meter rotate the Function Selector switch 

2

 from the 

OFF setting to any measurement setting. To Power OFF the meter rotate the 

Function Selector switch 

2

 to the OFF setting. By default, the meter will 

automatically Power OFF after 15 minutes of inactivity. Reactivate meter by 

pressing any button. To deactivate the automatic Power OFF feature, power 

the meter ON with the SEL button

10

depressed. When automatic Power 

OFF is deactivated, the   symbol will not be visible in the display. 

"SEL" (SELECT) BUTTON (FOR SECONDARY FUNCTIONS)  

The "SEL" button 

10

 activates the secondary function for each application 

accessible by the function selector switch 

2

. For current and voltage, it 

toggles between AC and DC. For the other functions, it switches between °F 

and °C, between Hz and % Duty-cycle, between Continuity and Resistance, 

and between Capacitance and Diode-test. The default function for each 

application is printed on the meter in white; the secondary function for each 

location is printed on the meter in orange.

"HOLD" (DATA HOLD) BUTTON

Press the "HOLD" button 

9

 to hold the measurement on the display. Press 

again to release the display and return to live measuring.

"RANGE" BUTTON 

The meter defaults to auto-ranging measurement mode 

. This 

automatically determines the most appropriate measurement range for the 

testing that is being conducted. To manually force the meter to measure in a 

different range, use the "RANGE" button 

7

.

1.  Press the "RANGE" button 

7

 to manually select measurement range 

(

 is deactivated on the LCD). Repeatedly press the "RANGE" 

button 

7

 to cycle through the available ranges, stopping once the 

desired range is reached.

2.  To return to auto-ranging mode, press and hold the "RANGE" button 

7

for more than one second (

 is reactivated).

"MAX/MIN" BUTTON 

When the "MAX/MIN" button 

8

 is pressed, the meter keeps track of the 

minimum and maximum value of the measurement as the meter continues 

to take samples. The first press of the "MAX/MIN" button 

8

 displays the 

Max value, the second press displays the Min value.
To return to normal measuring mode, press and hold the "MAX/MIN" button 

8

 for more than one second.      

BACKLIGHT BUTTON 

Press the Backlight button 

6

 to turn the backlight on or off. Backlight 

automatically turns off after approximately 3 minutes.

LEAD ALERT LEDs

When the Function Selector switch

2

 is rotated to a measurement setting, 

the Lead Alert LEDs

11

 will illuminate to ensure that the test leads are 

inserted into the appropriate jacks. The lights will automatically turn off after 

2 minutes. To disable the Lead Alert LEDs

11

, hold the Backlight button

6

and turn the Function Selector switch

2

 to any setting other than OFF. 

NOTE:

 Lead Alert function will reactivate by default when the meter 

powers OFF or when the Function Selector switch

2

 is rotated.
