➔ ABS (Absolute Deviation): The absolute deviation is the currently measured value minus preset nominal

value. Its calculation formula is: ⊿ABS = X – Y.

X is the currently measured value. Y is preset nominal value.

➔ % (percentage deviation): The percentage deviation is the percentage of the difference between the

currently measured value and the preset nominal value. Its calculation formula is: ⊿% = （X – Y）/ Y×100[%]

X is the currently measured value. Y is preset nominal value.

Comparator result output.

All signals are collector outputs with built-in pull-up resistor. Pul-up power source can

be internal +5V power source or exteran power source EXTV (default at EXTV).

Resistance of the built-in pull-up resistor is 4.7kΩ.

12,13 /EXT.TRIG Rising edge of this signal triggers measurement. Pulse width≥1μs. Low level drive

current approx. 5-10mA.

16,17,18 +5V

Internal +5V power output: Normally it is not recommended to use internal power

source. If the internal power source must be used, please make sure the signal’s

current is less than 0.3A and ensure the signal is well shielded from interference.

27,28 EXTV External DC power source input for comparator signal.

If using internal +5V power source, please reset the internal jumper connection.

30 /IDX

/IDX is valid after A/D conversion is finished.

When the signal is valid, the automatic tester will allow the next component to move

into measuring position. The currently measured result will be output when /EOM is

valid.

31 /EOM End Of Measurement: the signal is valid when the measured results and comparing

results are valid.

34,35,36 COM Reference ground for external power source EXTV.

3. Introduction to SCPI Commands

SCPI (Standard Commands for Programmable Instrument) is standard commands for programmable

instruments based on IEEE 488.2 common commands. SCPI commands include two parts: IEEE 488.2

Common Commands and Control Commands defined for SCPI instruments.

Common Commands, as defined by IEEE 488.2, are supported by the instrument. Syntax and semantics of

common commands must follow the rules of IEEE 488.2. Common commands are generally used to control

reset, self-test and status operations in stead of measurement. For more details, please refer to chapter IEEE

488.2 Common Commands.

Control Commands defined for SCPI instruments are used to measure, read data, switch ON/OFF a function or

a mode and so on. This chapter includes the following contents.

3.1 Command Structure

The SCPI is in a tree structure. The command on the top is called “root command” or called “root” in short. To

reach command of the lowest level, user must follow its route.

Command terminator It is a symbol to end the command. For example: NL (Line break symbol, as 10 in

ASCII code).

Colon (:) It means a command level, going to the next level.

Semic olon (;) It means multiple levels of commands.

Question mark (?) It means query.

Comma (,) It is a break between multiple parameters.

Space ( ) It is a break between commands and parameters. A symbol is used to represents

space In description of commands.

Quotation mark (“”) It means contents of the original citation, which will not be processed by command

analysis programm.

Asterisk (*) Commands follow an asterisk are common commands.

The following figure shows how to reach command of the lowest level by using colon and semicolon.

If sending command: AA:BB:EE;FF;GG

It means the same to send below three commands:

:AA:BB:EE

:AA:BB:FF

:AA:BB:GG

- 29 -

NX=XB1BXB2BXB3BXB4B

XB5BXB6BXB7B

≤10 NX: it is relative setting parameters.

Parameter’s value and unit follows symbol “=”.

Rules:

N1: Nominal value

N2: Q/D limits

N3: High limit of grade 1

N4: Low limit of grade 1





N9: High limit of secondary parameter

N0: Low limit of secondary parameter

After receiving data, the instrument will automatically

adjusted data into below format:

1) X1B: ASCII code of 0~9.

X2~XB6B: ASCII codes of 0~9 and decimal points.

XB7B: ASCII code of 0~2. Here XB7B is defined as below:

ASCII code of XB7B C L Z, Q

30H pF H Ω

31H nF mH KΩ

32H F H MΩ

2) N3~N8

XB1B: ASCII codes of “+” and “-”.

X2: ASCII codes of 0~9.

X3~X6: ASCII codes of 0~9 and decimal points.

X7: ASCII code of % (N2, N9).

3) N0, N9

XB1B: ASCII codes of “+” and “-”.


X7: ASCII code of 0~2.

4) N2


Note: N2 is only valid for secondary parameters D/Q. D

with high limit and without low limit. Q with low limit and

without high limit.

Examples and remarks:

(Symbols are used in the following

examples and remarks. Please change

to ASCII code when writing

commands.)

1) N1=122 The instrument adjusts it

as N1=12.0002 (7 bit) after

receiving. The last bit is code for

unit. For resistance measurement,

nominal value here is 12 MΩ. That

is:

N1 starts with numerical values

and ends with code of unit. Its first

bit must be 0~9, while other bits

contain 0~9 or decimal points.

After adjusted by the instrument, it

is less than 7 bit.

2) N2=12 The instrument adjusts it as

N2=12.000 (6 bit). That is:

N2 (high and low values of D/Q)

starts with numerical values and

ends with code of unit. Its first bit

must be 0~9, while other bits



is less than 6 bit.

3) N3=1% The instrument adjusts it

as N3=+1.000% (7 bit) after

receiving. The last bit is code for

unit. That is:

N3~N8 (high and low values) starts

with symbols or numerical values,

and ends with “%”. If it starts with

a symbol, the second bit must be

numerical values. Other bits must



is less than 7 bit.

47 NX=?P 4 Query setting values of the instrument. When the instrument

receives this command, it sends corresponding command to

the computer for one time in below format:

{ NX=XB1BXB2BXB3BXB4BXB5BXB6BXB7B}

According to command 46, the data is adjusted automatically

by the instrument as X2~XB6B:999999

48 P0 2 Trigger, same as pressing TRIGGER key on front panel.
