1.1 Product Introduction
(1) Easy testing conforming to standards
The unit allows pressure tests based on a wide variety of standards to be conducted.
The timer function and the comparative screening function using upper- and lower-
level values provide accurate test results. The unit does not operate until the output
voltage preset using the voltage adjustment knob is within
±
5% (output voltage
≦
1kV:
±
50 V) of the comparative voltage value, thus further ensuring accurate
readings.
(2) Fluorescent indicator
The large, easy-to-read fluorescent display permits quick checking of the testing
state and result.
(3) Analog Voltage Measurement
The voltage is digitally displayed on the fluorescent indicator. This value can also
be checked on the analog voltmeter.
(4) Zero-Toggle Switch
This function ensure that test voltage can be toggled on and off only at a sine wave
zero crossings, to prevent damage to the device under test if it happens to be faulty.
(5) Saving testing set values
This unit is provided with a function for saving the set values used in a test,
allowing quick switching between different testing set values to meet a variety of
standards and regulations. Up to 20 values may be saved.
The values immediately prior to a power shutdown are saved in the unit. These
values are valid at the next startup.
(6) REMOTE CONTROL BOX
The 9613 REMOTE CONTROL BOX (SINGLE) or the 9614 REMOTE CONTROL
BOX (DUAL) can be connected to the external switch terminal to perform 3158
start/stop control.
(7) External I/O
The external I/O terminal generates signals according to the state of the 3158. It
can be used to feed signals for the start and stop key.
(8) RS-232C interface as a standard feature
Automatic testing and saving of the test results are possible with the use of a
computer.
