6243/44 DC Voltage Current Source/Monitor Operation Manual
Caution-1
SAFETY PRECAUTIONS FOR THE 6243/44
Confirm all of the following points before connecting the 6243/44 and the DUT to prevent destruction of the
DUT due to an overload of voltage or current:
• The 6243/44 is in the standby mode. (OPERATE lamp is off.)
• No error or failure indication is displayed.
• The 6243/44 is grounded. (The ground pin of the power cable is grounded.)
• When using an ADC CORPORATION manufactured test fixture, connecting the INTERLOCK ter-
minal to the LID SIGNAL on the test fixture makes it possible to set the output to standby status by
opening and closing the lid.
When mounting the 6243/44 in a rack
• Make sure that the rack does not topple over if the 6243/44 is off balance.
• Be careful that the rack does not topple over when the slide rail is pulled out.
When the 6243/44 is used in the TR6143 Mode 1
The voltage limiter of the current source function only operates using the same polarity as that of the
source.
When the current source value is set to +0 A in the no-load status, or when negative current is generated
due to an error, the output terminal may deliver a negative supply voltage. (6243; -130 V, 6244; -26 V)
If these conditions pose a problem, use one of the following procedures.
• Set the value of current source to 10 counts or higher at all times.
• Use the Original Mode.
• Use the TR6143 Mode 2.
(In TR6143 Mode 2, the GPIB commands are the same as in TR6143 Mode 1. However, the hard-
ware configuration is the same as the 6243/44 so the voltage limiter operates using both polarities.)
