1.1 Introduction
TH2821A is a microprocessor-controlled portable meter with
low power consumption. It can measure six basic parameters,
they are inductance L, capacitance C, resistance R,
impedance |Z|, dissipation factor D and quality factor Q.
TH2821A can fulfill the measurement needs of various
component manufacturers and maintenance technicians.
1.2 Main Functions
1． Test Parameter
L-Q, C-D, R-Q and Z-Q.
2． Correction
OPEN: multi-frequency correction of open circuit;
SHORT: multi-frequency correction of short circuit.
3． Display Mode
Direct —— direct measurement value;
∆ —— absolute deviation;
∆% —— percent deviation.
4． Range Hold
When measuring a large number of components with
the same nominal value, this function can effectively
improve the measuring rate.
