"FAIL" state
「READY状態」
READY indicates that the tested object failed to pass the test set in the READY state. The
FAIL lamp will light up, accompanied by UPPER if the measured value exceeds the upper-
level value, or by LOWER if the measured value is below the lower-level value. If the
measured value deviates from the comparative-voltage range, the FAIL lamp will light up,
accompanied by both UPPER and LOWER. The FAIL-state screen is displayed for 0.5
seconds, and the unit then switches to the READY state. The FAIL state can be maintained

Using the inter-lock function
The inter-lock function is active when the INT.LOCK terminal is open, with the
following displayed:
To disable the function, connect the INT.LOCK terminal to ISO.COM and set it to
Lo. The unit changes to READY status once the inter-lock function is disabled.
For example, to ensure the safety of workers, the unit and the tested object are
placed in a box so that they are not in contact with each other. The door of the box
cover is also equipped with a switch that works in combination with the inter-lock
function. If a connection is made to the switch, the inter-lock function is enabled
when the box cover is opened. When the cover is closed, the function is disabled,
making the unit ready for testing.
All keys are inactive provided that the inter-lock function is active. As a result,
once the unit is mounted in the box, the settings cannot be changed. In such a case,
connect the setting adjustment switch the door switch such that these switches are
arranged in parallel, as shown below:

A buzzer sounds during PASS or FAIL screening and in the event of an error due to
improper key operations. Two buzzer volume adjustment knobs are provided on the
rear panel: one for PASS screening and one for FAIL screening. Volume
adjustments can be made using the knobs.
Tools required for adjustment

(2) Using a No. 0 Phillips screwdriver or 3-mm slotted screwdriver, adjust the
volume adjustment knob. To increase the volume, turn the knob clockwise. To
decrease it, turn it counterclockwise.
NOTE

If an excessive force is placed on the volume adjustment knob, it may be fractured.
During screening, the length of time the buzzer sounds depends on the settings for

NOTE
Command Format
The 3158 commands have the following structure.
+
Command
The command and the parameter are separated by " " ( one character space )
If there is no parameter, send the delimiter after the command.
The command may consist of both upper and lower case letters.
Make sure to use one character space as the separator between the command and
the parameter.
(1) When the command contains a parameter
:CONF:CUPP5.0(+delimiter)
The command format consists of the command ":CONF:CUPP" followed by
the separator "".Then follows the parameter "5.0". Following the
parameter comes the delimiter.
(2) When the command contains no parameter
:STOP ( + delimiter )
The command format consists of the command ":STOP" immediately followed
by the delimiter.
The meaning of the delimiter is to separate commands and data. When the 3158
receives the delimiter, it starts analysis of the command.
(4) When the command contained an Transmission error,
TIME OU T ERR ( + delimiter ):
Time out error (When the delimiter is not transmitted for
approximately 10 seconds)
SI0 ERR : Serial Transmission error
Parameters
The 3158 uses parameters composed of decimal numbers. There are three different
formats for decimal data: NR1, NR2, and NR3. Each has two values: one with a
code and one without it. A value without a code is regarded as a positive number.
If a number exceeds the accuracy resolution of the 3158, the value is rounded up or
down.
NR1 format: Integer data
+12, -23, 34
NR2 format: Fixed point numbers
+1.23, -23.45, 3.456
NR3 format: Floating point numbers.
+1E-2, -2.3E+4
The format that contains all three formats is referred to as the "NRf format." In the
3158, a format is specified for each command. For details, see 7.5, "Transmission
and Response Formats."
Delimiter
Depending on transmission direction, the delimiter is as follows.
From computer to 3158: CR or CR + LF
From 315 8 to computer: CR + LF
