About this manual
This is the operation manual for the TOS5050A/TOS5051A Withstanding Voltage
tester.
■ ROM version of the product to which this manual applies
• TOS5050A: Ver.1.0X
• TOS5051A: Ver.1.0X
To check the version number, refer to 5.2 “Checking the tester Operation.”
When you contact us for any information about the tester, please indicate the ver-
sion number and the serial number of the tester. The serial number is written on the
rear panel of the tester.
• To those using the old model TOS5050/5051
The SIGNAL I/O connector on this tester is not compatible with that on the
old model TOS5050/5051 (different pin assignments). Therefore, the 14-
pin Amphenol plug that is supplied with the tester cannot be shared
between the new and old models.
If you connect the Amphenol plug which you use for the old model to this
tester, testing is not possible because the protection is not released.
To use the Amphenol plug for the old model to this tester, you have to change the
wiring for the interlock function. For details, refer to section 6.3.2 Remote Con-
trol through the SIGNAL I/O Connector and 6.3.3 Interlock Function.
Testing is not possible when
you open the package.
If you turn on the power to the tester simply after taking the tester out
from the box, testing is not possible because the interlock function is
activated.
For a description of the interlock function, see section 6.3.3, “Interlock
Function” in this manual. Then, operate the tester appropriately using the
interlock function.
NOTE
TYPE A
It is marked “TYPE A” to distinguish
from the plug for the old model.

To the supervisor in charge of operation
• If the operator does not read the language used in this manual, translate the manual
into the appropriate language.
• Help the operator in understanding this manual before operation.
• Keep this manual near the tester for easy access by the operator.
For your own safety (to avoid electric shock)
While the tester is delivering its test voltage, never touch the following areas, or else,
you will receive electric shock, and run the risk of death.
• the output terminal
• the test leads connected to the output terminal
• the Device Under Test (DUT)
• any area electrically connected to the output terminal.
• any area electrically connected to the output terminal immediately after the output
has been cut off in the DC test mode.
Also, electric shock or accident may occur in the following cases:
• the tester being operated without grounding.
• if the gloves for electrical work are not used.
• approach any part connected to the output terminal while the power of the tester is
turned on.
• approach any part connected to the output terminal immediately after the power of
tester has been turned off in the DC test mode.
