Measurement 
displays 

Value 

R/Q, C/D, C/R, L/Q, Z/ θ, L/R 
*The resolution of primary display (L, 
C, R or Z) is five digits. 
*The resolution of secondary display 
(D, Q, R with C, or R with 
L) is four digits. 
*The resolution of secondary display 
(θ) is 2 digits after decimal place.

 

Delta% 

DELTA% shows the percent deviation 
of the measured L, 
C, R or Z value from a saved 
NOMINAL VALUE. The deviation is 
indicated.

 

Delta 

Delta is similar to the DELTA% except 
that the deviation is shown in suitable 
units (ohms, henries, etc.)
