Programmable AC Source 61601/61602/61603/61604 Quick Start Guide
Meanwhile, the AC source does the memory, data and communication self
test. After the routines of the self test are done, the display shows the
MODEL number, and the serial number of the AC source, and it shows an
"OK" at the right side of each test item indicating that the item is no problem.
It takes about six seconds to complete the routines of the self test. Then
the display shows the versions of software as below.
MODEL : 61602

3. REMOTE
If any failure is detected on a certain item, an "ERROR CODE" will be
shown at the right side of that item. The error messages and
trouble-shooting are shown on 6.2 in Programmable AC Source 61601/
61602/61603/61604 User's Manual. The test item "3. REMOTE "shows"
<EMPTY>, if the option board (with GPIB and RS-232) is not connected.
After finishing memory, data and communication self-test, the AC source
do the power output self test. In this procedure, the output relays are in
OFF status to sure not harming the load connecting on output terminal.
The AC source will program 300Vac and measure the voltage. If the
measured voltage is over 300V±5V, the power self-test is failed, and the
display will show "NG". If it's ok, the display is shown as below. Then, it
changes to MAIN PAGE automatically.

1. The user can do diagnosis if error or NG happened
in power-on self-test procedure. Please see 6.2
in Programmable AC Source 61601/61602/61603/
61604 User's Manual.
2. The inner digital circuit of AC source maybe not
reset if turn off power then turn on immediately.
