ERRATA:

 

 

 

On

Page 3-1, in Paragraph 3-2,delete step (b)

and

reletter

following steps

appropriately;

change

step

(c) to read: “Set range switch

to

desired

operating mode. . . ”;

change

step (d) to

read: “Ad-

just

coarse

and fine

voltage controls

until. . ."

On Page 5-4, in Paragraph 5-16,change steps (b) through (d) to read as follows:

b. Set METER switch to low current range and RANGE switch to high voltage mode.

c, Turn on supply and adjust VOLTAGE controls until front panel meter indicates exactly 300mA (0.5 ampere for Model 6206B supplies).

d. Differential voltmeter should read 1.5 ± 0.045Vdc.

CHANGE 1:

In the replaceable parts table, make the following change:

Terminal Strip: Add, HP Part No. 0360-0401.

CHANGE 2:

In the replaceable parts table, make the following c h a n g e s :

S1: Change to HP Part No . 3101 - 1248 .

In miscellaneous:

Panel, Front: Change to HP Part No. 06205-00004.

CHANGE 3:

In the replaceable parts table and on the schematic make the following changes:

Tl: Change to HP Part No. 9100-2611.

The primary wiring of the unit is now as shown below.

CHANGE 4:

The Serial Prefix of this unit has been changed to 1140A. This is the only change.

ERRATA :

in the instructions for auto-series operation in paragraph 3-33,change the third sentence to r e a d :

“The value of Rx is this voltage divided by the

voltage programming current of the slave supply (l/Kp, w h e r e Kp is the r e s i s t a n c e p r o g r a m -

ming coefficient for constant voltage operation). “ The voltage programming current of the Model 6205B is 1/200 ohms per volt, or 5 milliamps.

On page A-1 under Description, add “6205B” to the first sentence. Also change the second sentence of the second paragraph to read, “The trip voltage is determined by the setting of the crowbar adjust control on the front panel (except in the Model 6205B, where it is accessible through

ahole in the top cover). “ Also on page A-1, change the last part of the third step under Oper- ation to read “. . . output goes to O volts or a small positive voltage. “

On the schematic and in the parts list, change resistor R12 (for both dual supplies) to 1.4k 5% 3W 30 ppm, HP Part No. 0811-1804.
