Agilent Technologies Water Heater E4350B Manual De Usuario

Some of the front panel keys perform two functions, one labeled in black and the other in blue. You access the blue function
by first pressing the blue 

 key, which is not labeled. When the Shift annunciator is on, you will know you have access

to the key’s shifted (blue) function.

The 

 key is an erase key. If you make a mistake entering a number and have not yet entered it (have not pressed

), you can delete the number by pressing 

. You may delete as many numbers as you wish by repeatedly pressing

this key.

When the Agilent SAS is turned on, it asserts the state stored in EEPROM memory location 0. For a new
unit, this is the factory default (*RST) state. The following procedures assume that the factory default
state is still in location 0 (see Turn-On Conditions in chapter 5 for details).

The tests in Table 3-1 check the basic voltage functions with no load connected to the Agilent SAS. These test are  possible
only from the front panel when the unit is operating in Fixed mode. The VOLTS display will show various readings. Ignore
the AMPS display.

Either leave the output terminals open or connect them to a voltmeter.

If the Dis annunciator is on, turn it off by pressing 

Press 

 key

VOLT 0.000

Default voltage setting. CV annunciator should be on. (If CC annunicator
is on, increase the current by pressing 

one or more times until

CC turns off and CV turns on.)

Press

 

VOLT 40

Program output to 40 volts.

Press 

40.00

Enter the voltage. Meter mode displays output voltage. During these
tests, there may be a small (relative to full output) AMPS reading that
will be ignored.

Press 

 several

times

Voltage decreases several millivolts each time you press the key.

Press 

 the same

number of times

Voltage increases several millivolts each time you press the key.
