Handler Interface     

 This section provides information of micro ohmmeter built-in handler interface. Include:

• Pin Assignment
• Circuit Diagram
• Timing Chart

Built-in handler interface outputs signals that indicate the end of a measurement cycle, the result of bin sorting by the comparator. In addition, the instrument accepts input of external trigger. To view the signals easily integrate this instrument with a component handler or system controller. This means it can be fully automated the tasks component inspection, component sorting, and processing of quality management data for higher manufacturing efficiency

This means that once the handler has received this signal, the next DUT can be connected to the UNKNOWN terminal. However, measurement data are not available until the /EOM signal is output.
31	/EOM	Output	“End of measurement cycle” signal. When the output of this signal is generated, the measurement data and sorting results are available

• The LED (anode side) is connected to the pull-up power supply voltage.

Output Signal:

• Each output signal is generated via an open collector by using a photo-coupler.
• The voltage of each output is obtained by connecting pull-up resistors, inside or outside of the device.

About RS-232C

Connect the controller i.e.) PC and PLC to the RS-232 interface using RS-232 DB-9 cable. The serial port uses the transmitter, receiver and signal ground lines with RS-232 standard. It does not use the hardware handshaking lines CTS and RTS.

Note:

• Use only DB-9 cable
• Cable length should not exceed 2 m.

SCPI Language:

Standard commands for programmable Instruments (SCPI) is fully supported by the RS-232 interface.

Command Structure:

LCR meter commands are divided into two types:

• Common commands
• SCPI commands

Common commands are common for all devices. SCPI commands are used to control the each LCR meter functions. The SCPI commands are represented using tree structure in three levels. The highest level commands are called the subsystem commands and the lower level commands are legal only when the subsystem commands have been selected.

Colon (:) A colon is used to separate the higher level commands and the lower level commands.

Semicolon (;) A semicolon is used to separate two commands in the same message and it does not change the current path.

Command Tree Example:

All commands follow the functional command order.

• DISPlay Subsystem
• FUNCtion Subsystem
• FREQuency Subsystem
• VOLTage Subsystem
• APERture Subsystem
• FETCh Subsystem
• COMParator Subsystem
• LIST Subsystem
• CORRection Subsystem
• TRIGger Subsystem
• BIAS Subsystem
• FILE Subsystem
• ERRor Subsystem

Common Command:

• *TRG
• *IDN?
• *SAV
• *RCL

Each subsystem command is patterned as follows.

1. Subsystem command name
2. Command Tree (Subsystem command only)
3. Compound Command Name
