Chapter 1 General Introduction
Thank you for purchasing our product. The contents of the shipment should be as listed in
the packing list. If the contents are incomplete, if there is mechanical damage or defect, or
if the instrument does not pass the power-on self tests, please notify our company.
1.1 Foreword
TH2817B is a precision LCR meter with high accuracy, good stability, and wide
measurement range. Controlled by a 16 bits MPU, TH2817B can be used for evaluating LCR
components, materials and semiconductor devices over a wide range of frequencies (50 Hz
to 100 kHz) and test signal levels (0.1V, 0.3V, 1V). With its powerful function, excellent
performance, perspicuous LCD display and easy menu operation, TH2817B is suitable for
high speed measurement need on product line and high accuracy and stability
measurement need in laboratory. By using the Handler interface, IEEE488 interface
(optional), and RS232C interface, TH2817B can easily be used for automatic test system
and computer remote control.
The instrument provides variable test conditions, typical conditions are as follows:
z
Test signal frequency
10 typical frequency points available from 50 Hz to 100 kHz: 50Hz, 60Hz, 100Hz,
120Hz, 1kHz, 10kHz, 20kHz, 40kHz, 50kHz, 100kHz.
z
Test signal level
Programmable signal level from 0.01 V to 2.00 V in 0.01 V resolution.
z
Measurement speed
Fast, Medium and Slow measurement speed can be selected. Using the averaging rate
(from 1 to 255 programmable) function, you can get more stable measurement
results.
z
Constant selectable source resistance
30 Ωor 100Ω
z
Correction function
The OPEN, SHORT correction for correcting the stray admittance, the residual
impedance, and the other errors can be performed. The correction function has two
kinds of correction methods. In one method the open and short correction can be
performed at all of the frequency points, and in the other method the open, short
correction can be performed at the frequency points you specify.

TH2817B provides 3 display modes and 2 kinds of sorting modes:
z
Direct:
The actual measurement results are displayed.
Absolute deviation (ΔABS):
The difference between the measured value of the
DUT and a previously stored reference value are displayed.
Percentage deviation (Δ%):
The difference between the measured value of the
DUT and a previously stored reference value are displayed as a percentage of the
reference value.
z
Component sorting:
Two comparison modes, absolute deviation and percent
deviation can be used.
4-bin sorting:
3 PASS bins, 1 FAIL bin, and 1 AUXiliary BIN.
TH2817B provides several communication interfaces which make it easy to output the
measurement results to other equipments (for example computers), or build an automatic
test system.
z
RS232C interface:
RS232C interface makes it easy to communicate with other
quipments. You can set the measurement functions and input the parameters through
RS232C interface instead of keyboard on front panel.
z
IEEE488 interface (optional):
IEEE488 interface helps instrument to build an
automatic test system with computer and other measurement instruments.
Command of RS232C and IEEE488 interfaces are programmed in the format of
common SCPI.
z
HANDLER interface:
By using the handler interface, the instrument can easily be
combined with a component handler, and a system controller to fully automate
component testing, sorting, and quality control data processing.
TH2817B has the file function to store the set parameters, limit parameters and list sweep
parameters as a file in the internal nonvolatile memory, so that the setups can be easily
reloaded, and the defult file will be automatically reloaded when TH2817B is turned on.

1.2.3 Warm-up time
More than 20 minutes after the instrument is turned on.
1.2.4 Notices
zPlease do not operate the instrument in the place that is vibrative, dusty, under direct
sunlight, or where there is corrosive air.
zAlthough the instrument has been specially designed for reducing the noise cased by
ac power, a place with low noise is still recommended. If this cannot be arranged,
please make sure to use power filter for the instrument.
zPlease store the instrument in the place where temperature is between 5 and 40℃℃,
humidity is less then 85% RH. If the instrument will not be put in use for a time,
please have it properly packed with its original box or a similar box for storing.
zDon’t frequently turn on and off the instrument, doing so will lead to the loss of the
calibrated data and the data saved by users.
1.3 Dimensions & Weight
Dimensions: 270×120×380 (mm3)
Weight: approx. 3kg
1.4 Safety Summary
The following general safety precautions must be observed during all phases of operation,
service, and repair of this instrument.
zGround the instrument
To avoid electric shock hazard, the instrument chassis and cabinet must be connected to a
safety earth ground by the supplied power cable with earth blade.
zDO NOT operate in an explosive atmosphere
Do not operate the instrument in the presence of flammable gasses or fumes. Operation of
any electrical instrument in such an environment constitutes a definite safety hazard.
zKeep the instrument away from live circuits
Operator can not remove instrument’s cover. Component replacement and internal
adjustments must be made by qualified maintenance personnel. Do not replace
components with the power cable connected. Under certain conditions, dangerous
voltages may exist even with the power cable removed. To avoid injuries, always
disconnect power and discharge circuits before touching them.

zDO NOT attempt service or adjustment alone
Do not attempt internal service or adjustment unless another person, capable of rendering
first aid and resuscitation, is present.
zDO NOT substitute parts or modify instrument
Because of the danger of introducing additional hazards, do not install substitute parts or
perform unauthorized modifications to the instrument. Return the instrument to our Sales
and Service Office for service and repair to ensure that safety features are maintained.
1.5 Electromagnetic Compatibility
This product has been designed and tested to the requirements of the Electromagnetic
Compatibility (EMC) Directive. To use a properly shielded cable or shielded coaxial cable to
connect each of the ports to their respective controllers, peripherals, equipments or
devices may ensure to meet the requirements.
