Parameter B
（secondary
parameter）
The UTR2810E/2811E can simultaneously measure two different parameter combinations of the measured impedance
in one test cycle. The primary and secondary parameters are as follows:
Z is positive value，L/C/R has positive and negative value.
When C measuring, the primary parameter display "-"，the actual device under test is inductive；
When L measuring, the primary parameter display "-"， the actual device under test is capacitive；
When R measuring，if R appears R "-"，it because over clear, please do clear operating correctly.
UTR2810E/2811E provides 42 measurement parameter combinations: primary and secondary parameter

3.2.2 Frequency

UTR2810E/2811E provides 4 common test frequency：100 Hz，120 Hz，1 kHz 和 10 kHz.

3.2.3 Electrical Level

UTR2810E/2811E provides 3 commin test signal voltage: 0.1V，0.3V and 1.0V. The current test signal voltage will
display in the the signal voltage indication area below the LCD.

3.2.4 Speed

UTR2810E/2811E provides three test mode FAST，MED and SLOW. In general, the slower the test speed, the more
stable and accurate the test results.
FAST: 43ms
MED: 185ms
SLOW: 350ms
