TH2829X Series Operation Manual Chapter 8 Performance and Test
155
8.6.5 Frequency
Connect frequency meter to ground terminal. The test terminal of the frequency
meter is connected with H
CUR.
Change the frequency as: 20Hz, 100Hz, 1kHz,
10kHz, 100kHz, 200kHz
（TH2829AX is 200kHz）. The reading of frequency meter
should meet the demand of the test signal frequency in this chapter.
8.6.6 Measurement accuracy
Basic parameters are R, L, C and D, so measurement accuracy is mainly about R,
L, C and D.
8.6.7 Accuracy of C and D
Function C
p
-D
Test frequency 100Hz 1kHz 10kHz 100kHz Test respectively
Level 1V
Range AUTO
Bias 0V
Speed Slow
Open and short correction should be made before testing. Connect standard
capacitors: 100pF, 1000pF, 10nF, 0.1uF, 1uF and change the frequency. The error
capacitance C between reading and nominal value should be in the range ruled in
this chapter, dissipation D should be in the range ruled in this chapter.
8.6.8 Accuracy of L
Test condition:
Function L
s
-Q
Test frequency 100Hz 1kHz Test respectively
Level 1V
Range AUTO
Bias 0V
Speed Slow
Open and short correction should be made before testing. Connect standard
inductors: 100μH, 1mH, 10mH, 100mH and change the frequency. The error
between reading and nominal value should be in the range ruled in this chapter.
8.6.9 Accuracy of Z
Test condition:
Function Z-θ
