DANGER
To avoid any life-threatening electric shock accidents, ensure that the
following rules are observed.
･
The AC Withstanding Voltage HiTester is a dangerous product which
discharges high voltages. To prevent getting electrocuted, always
wear high-voltage protective rubber gloves when carrying out any
operation.
･
Be careful when using the product and ensure that you do not touch
this product, any tested object that is connected or any H.V. TEST
LEAD, etc.
･
Make sure that no high voltage is being applied to the output,
confirm the following items, and connect the H.V. TEST LEAD.
(1) The analog voltmeter reads 0 kV.
(2) The DANGER lamp is OFF.
(3) The TEST lamp is OFF.
･
In the TEST state, never touch the output-voltage terminal, H.V. TEST
LEAD, or tested object.
･
Even following a test, there may be a residual voltage at the output
terminal. Therefore, before touching the output-voltage terminal, H.V.
TEST LEAD, or tested object, make sure that no high voltage is being
applied between the output terminals.
NOTE
･
If the HIGH and LOW voltage output terminals short-circuit or a dielectric
breakdown occurs in the tested object during the test, noise will be generated and
such noise may lead to a malfunction of this unit or of a nearby electronic device.
If this problem occurs, connect a ferrite core or a resistor to the H. V. TEST
LEAD (high voltage side).
When using a resistor, choose one appropriate for the power rating and withstand
voltage. Also, be alert to any drop in test voltage.
Beware of electric shock when connecting the resistor.
･
Do not the test lead and the EXT/IO cable arranged closely to each other.
Doing so may lead to a ma l functio n of the external control due to a noise.
Additionally, if the test lead touches to other metallic parts, it may cause an
increase in leakage current.
Prevent the test lead from coming into contact with other parts as much as possible .
(1) Make sure the analog voltmeter is at 0 kV and the DANGER lamp is OFF, and
the TEST lamp is OFF.
(2) Connect the LOW terminal probe to the tested object. Fasten the probe securely
to prevent it from loosening during a t est.
(3) Following the procedure described above, connect the HIGH terminal probe to
the tested object.

2.10 Startup Inspection
To ensure safe testing, check the following before starting operation:
Breaking current
(1) Calculate the resistance based on the output voltage to be set and the upper level
value, and then provide a resistor suitable for the resistance.
(Output voltage÷Upper-level value (Breaking current) = Resistance)
A high-voltage resistor with a power rating larger than the power calculated
from the output voltage and resistance is recommended.

(2) Set an upper-level value.
(3) Connect the resistor to the test lead.
(4) Increase the output voltage beyond the set value, and make sure the current is
cut off (i.e., make sure the unit is in the FAIL state).
Analog voltmeter
(1) Before turning on the power, make sure the analog voltmeter is at 0 kV.
(2) If the voltage reading is not at zero, adjust the value to zero using a slotted
screwdriver.
Inter-lock
If the Inter-lock function is set, make sure the Inter-lock function works properly
before starting operation.
Key inspection
(1) Turn off the power, and unplug the power cord from the power outlet.
(2) For both the START and STOP keys on the front panel of the unit, press the
center of the key, and make sure you feel it click. The click is less noticeable
when the edges of the keys are pressed.
* Clicking
When a key is pressed slowly, there is a moment of slight resistance and a
feeling that the key cannot be pressed any further. When the key is pressed
further after this point, a clicking sensation can be felt.
(3) If you do not feel a click, the key may be broken.

Note that the output waveform may be distorted when con ducting an AC
withstand voltage test for a voltage-dependent device or object (e.g., ceramic
capacitor). Excessively large distortion may damage the device or tested object.
When the device or tested object is a capacitive load, resonance may occur (when
conducting an AC withstand voltage test) with the coil inductance of the output
high-voltage transformer, depending on the capacitance value. This condition may
generate several tens of volts at the voltage output terminal before the test is

touching the output-voltage terminal, test lead, or tested object, make
sure the analog voltmeter is at 0 kV, the DANGER lamp is OFF, and

If the measured voltage deviates from the upper- or lower-level value during the test,
the unit switches to the FAIL state and immediately stops outputting a voltage. The
FAIL state can be divided into UPPER FAIL and LOWER FAIL states.
･
UPPER FAIL indicates that the measured voltage has exceeded the upper-level
value.
･
LOWER FAIL indicates that the measured voltage has dropped below the lowerlevel value.
(When the lower-level value is set to OFF, LOWER FAIL is ineffective.)
With a comparative voltage value set, if the output voltage deviates from the
comparative-voltage range, the unit switches to the FAIL state and UPPER,
LOWER,andFAIL light up.
The FAIL state is held using the FAIL Hold function. Refer to Section "4.2 FAIL Hold Function".

Connections for the inter-lock function (example)
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:

6.2 Buzzer
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
No. 0 Phillips screwdriver or 3-mm slotted screwdriver
(1) Check the analog voltmeter and the DANGER lamp to make sure a voltage is
not being output.
(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
Decrease
Increase
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
the PASS and FAIL hold. For more about the PASS hold setting, see "4.1 PASS
Hold Function," and for more about the FAIL hold setting, see "4.2 FAIL Hold
Function."

7.3 Command Transfer Methods
1
NOTE
The command is issued from the computer.
When the 3158 receives the incoming command from the computer, it executes the
processing specified by the command.
When 3158 has completed processing of the command, it always returns a response
to the computer.
When the computer has confirmed the response, it sends the next command.
RMT lights up on the screen during interface communication.
･
Every time the computer has sent a command, a response is always returned.
Make sure that the computer only sends the next command after it has received
the response to the previous command issued from the 3158.
If multiple commands are sent consecutively, the 3158 may not execute the
commands, or command errors may occur.
･
There is a need to add ":" to the front of the command except standard commands
in the instrument.

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.

Response format
When a command is sent to 3158 processes the command. When processing is
completed, 3158 always returns a response.
(1) When there is no information from 3158,
OK ( + delimiter )
(2) When there is information from 3158 (measurement values, etc.),
Response character string related to the command ( +delimiter )
(3) When the command contained an error,
CMDERR(+delimiter) : Command error
EXEC ERR ( + delimiter ) : Execution error
(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
