Before Us

.1 Check of External Appearance and Accessories

When the unit is delivered, check and make sure that it has not been damaged in transit. If the unit is damaged, or fails to operate according to the specifications, contact your dealer or HIOKI representative.

1.1 Check of External Appearance and Accessories

────────────────────────────────────────────────────

.2 Shipping Precautions

If reshipping the unit, preferably use the original packing.

If this is not available, use the following procedure. (1) Wrap the unit in plastic sheeting.

(2) After wrapping cushioning material around the unit, pack it into a

cardboard box, and then seal up the box with adhesive tape.

────────────────────────────────────────────────────

1.2 Shipping Precautions

────────────────────────────────────────────────────

.3 Notes on Use

(1) If you change the communication conditions of the 3157 while using it, you

should immediately turn the power off and on again. If you do not do so, the communication conditions will not be changed to the new ones.

(2) Always be sure to secure the RS-232C cable to the 9593-02 unit by tightening

up the fixing screws provided.

(3) Program messages sent just after the power has been turned on are executed

after the self test has terminated.

(4) It is vital that the proper data format is used when inputting commands with

data values to the 3157 unit.

(5) For details of the various functions, refer to the instruction manual for the

3157 unit.

.4 Installing the RS-232C Interface

WARNIN

CAUTIO

To prevent electrical shock, before adding or replacing the RS-232C interface, check that the power for the unit is off and the power cord and connectors are disconnected. [The fixing screws must be firmly tightened or the input unit may not function up to specification, or may even fail.]

To avoid the danger of electric shock, never operate the unit with an RS-232C interface removed. If you should wish to use the unit after removing an interface, fit a blank panel over the opening of the removed unit.

When inserting in the interface, hold the metal plate. Directly touching the board may cause static electricity and lead to damage of the instrument. (Using the wrist strap for preventing static electricity when inserting is recommended.)

The space for fitting the 9593-02 RS-232C INTERFACE in the rear panel of the 3157 is covered with a blank panel. Follow these three steps to install the 9593-02 interface:

(1) Remove the fixing screws, and take off the blank panel. (2) Insert the 9593-02 RS-232C INTERFACE into the exposed slot in the rear

of the unit in the figure below.

(3) Push the 9593-02 firmly into place, and fix with the screws removed in

step 1.

Overvie

.1 Introduction to the RS-232C Interface

By connecting the 9593-02 RS-232C INTERFACE to the 3157 AC GROUNDING HiTESTER, it is possible to control all the functions of the main unit (except for powering on and off) via the RS-232C bus.

────────────────────────────────────────────────────

2.1 Introduction to the RS-232C Interface

────────────────────────────────────────────────────

.2 Features

(1) All of the functions of the 3157 main unit, except for powering on and off, can

be controlled via the RS-232C interface. However, the ":STARt" command works in a state in which the momentary OUT settings are disabled even

though the momentary OUT settings have been set. (2) The beeper sound can be turned on and off. (3) The unit can be reset. (4) Test results can be printed on the optional 9442 PRINTER. (5) Connecting with the optional 3155 LEAK CURRENT HiTESTER enables

testing and the test results can be saved and printed together with the 3155

leakage current test results.

Connection to the 315

Attaching optional 9593-02 RS-232C INTERFACE to 3157 enables testing when connected with 3155. 3155 sends command to 3157 to start testing and receives test results when the 3157 testing is complete. The test results can be saved and printed together with the 3155 leakage current test results. For usage for the 3155, see 3155 (-01) Instruction Manual.

.2 Communication Methods by the RS-232C

In order to control the 3157 by the RS-232C, there are several kinds of messages. Of these, program messages are those received by the 3157 from the computer, while response messages are those sent from the 3157 to the computer.

Program messages

Message

Response message

Command message Query messages

(1) Program messages

Program messages are command messages or query messages.

・Command messages are orders for controls of the 3157, such as for making

unit settings or for reset or the like. Example :TIMER_<data>

(Command message which enables and disables the test time)

・Query messages are orders for responses relating to results of operation,

results of measurement, or the state of 3157 settings. A question mark "?" is suffixed at the end of the command. Example

(Queries the current test time enablement)

:TIMER?

(2) Response messages

It represents the response data for query messages from the 3157. Example

(Test time is currently enabled.)

:TIMER_ON

NOTE

A space is represented by "_" in the examples.

Program message

Response message

────────────────────────────────────────────────────

6.2 Communication Methods by the RS-232C

────────────────────────────────────────────────────

.3 Message Format

The commands for the 3157 are as far as possible mnemonic. Furthermore, all commands have a long form, and an abbreviated short form.

.3.1 Program Message

The program message is made up from header and data portions. Example Command message to set test time to ON

:TIMER_ON

↑↑

: Header portion : Data portion (ASCII-format text or numeric values. Some

messages have no data portions...query messages, etc.) A command header can be abbreviated. The whole command form is referred

to as the "long form" and the abbreviated form as the "short form." In this manual, the short form is written in upper case letters, and then this

is continued in lower case letters so as to constitute the long form. Either of these forms will be accepted during operation, but intermediate forms will not be accepted. Further, during operation both lower case letters and upper case letters will be accepted without distinction.

For "TIMER", either "TIMer" (the long form) or "TIM" (the short form) will be accepted. However, any one of "TIME", or "TI" is wrong and will generate an error.

.3.2 Response Messages

It represents the response message for query messages from the 3157. Response messages generated by the 3157 are in long form and in upper case letters. Example :TIMER_ON

(Test time is currently enabled.)

NOTE

────────────────────────────────────────────────────

If an error occurs when the query message is received, the query does not produce response message.

6.3 Message Format

────────────────────────────────────────────────────

.4 Headers

(1) Program message headers

There are three types of header: simple headers, compound headers, and particular headers.

・Simple header

A header consisting of a single word beginning with a letter. Examples :HEADer etc.

・Compound header

A header consisting of a sequence of words separated by colons. Examples :CONFigure:CURRent, MEASure:RESistance?, etc.

・Particular header

A header beggining with an asterisk (*) to indicate that it is a particular command. Examples *RST etc.

(2) Response message

Headers in response messages can be enabled or disabled by using the "HEADer" command.

Example When test time is enabled: :TIMER?

(Query message asking for the current enablement state of the test

time) Response message when headers are on. :TIMER_ON

↑↑

: Header portion : Data portion

Response message when headers are off. ON

Data portion only
