 Test Frequency 

 
Default testing frequency is 1KHz. Push "

FREQ

" key to select 

the desired test frequency. 
 

 L/C/R Function Selector 

 

Press "

L/C/R

" pushbutton to select the desired L, C or R 

function.  

 

 Relative 

 

Press the "

REL

" key to enter the relative mode and store the 

display reading as a reference value.    It will then display all 
subsequent readings relative to the reference value. Press 
"

REL

" button again to exit the relative mode. 

 

Notes: 

1.  The relative mode can not be activated if the display value 

is either "

OL

" or "

0000

". 

2. Relative mode is only available in manual ranging; 

however, activation while in auto-ranging will automatically 
set the meter to manual ranging and cause calibration 
prompts to be displayed in the relevant ranges. 

3.  The relative mode cannot be activated if the meter is set at 

auto-ranging with data hold activated. 

 

 Tolerance   

 
There are 1%, 5% and 10% tolerance range.    To enter this 
tolerance mode, insert the appropriate component as a 
standard value into the socket or connect the component to 
the test probes, then press the "

TOL

" pushbutton to set this 

value, as the standard reference tolerance.  Similarly, any 
value which appears on the LCD display, such as 

DH

 or 

MAX/MIN/AVG

, can be used as a standard value to sort 

components.    Press this button again to cycle through 1%, 
5% and 10% tolerance as required. 
This function is designed for convenient component sorting.   
An audible tone of “Be-Be-Be” will sound whenever the 
component under test exceeds the setting tolerance. 
Conversely, a single tone of “Be” indicates the component is 
within the setting tolerance.
