Tonghui TH2840 Series - Accuracy of L; Accuracy of Z; Accuracy of DCR

130
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 the instrument reading and the
standard value should be within the allowable error range specified in this chapter for L accuracy.
8.6.9 Accuracy of Z
Test condition:
Function Z-θ
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 AC resistors: 10Ω,
100Ω, 1kΩ, 10kΩ, 100kΩ and change the frequency. The error between the instrument reading and
the standard value should be within the allowable error range specified in this chapter for the
accuracy of |Z|.
