Chapter 1 General introduction
This chapter provides brief and concise description of instrument’s
specifications and functions.
1.1 Brief
introduction
As a newly developed instrument, TH2810B Series Component Parameter
Testers offer fast, reliable, and versatile testing at a low cost. It can
automatically measure component parameters, including inductance (L),
capacitance (C), resistance (R), impedance (Z), quality factor (Q), and tangent
of dissipation angle (D), etc. This instrument, which merges powerful functions,
excellent performances and simple operation into a whole, can satisfy both the
need for fast test in factories, and the requirement of high precision and stable
measurement in laboratory.
Compared with general component parameter testers, instruments of TH2810B
make improvements in the following aspects:
1. To meet requirements in different situations, the instrument has two sets of
selection programs, and parameter setup is of many digits and high
resolution rate. The instrument can be connected with automatic meter
through interfaces to realize automatic measurement.
2. The instrument provides RS232C interface to effectively communicate with
computer and make it possible to remotely control and collect data.
3. The instrument applies the design method of invariable resistance of signal
source, and it ensures that voltage or current signal in one tested
component does not change with the adjustment of range, to avoid being
hard to select range for tested component which is at the edge of range.
4. The instrument has the functions of locking key and saving state. It can
reduce workers’ incorrect operation, and make personalized default state
possible.
TH2810B Series Component Parameter Testers include TH2810B LCR meter,
TH2618B capacitance meter, and TH2775B inductance meter. And they differ in
measurement parameters (referring to Table 1-1 Measurement Parameters
Table in § 1.2.2). TH2618B and TH2775B only have some functions of TH2810B,
so this manual is applicable to TH2810B and the contents which are only
applicable to TH2618B or TH2775B are marked.
1.2 Specifications
1.2.1 Measurement terminals
There are five terminals, namely HD, HS, LS, LD and GND.
