B.4

DISP:CONTrast? QUERY

DISP:CONT?

Syntax:

Short Form: DISP:CONT?

Long Form: DISPlay:CONTrast

Description:

Returns the brightness level set by DISP:CONT.

Return Format:

B.5

FETCh? QUERY

FETC?

Syntax:

Short Form: FETC?

Long Form: FETCh?

Description:

Measures actual output voltage and current. The query performs a measurement and returns
the value of DC output current in amperes and DC output voltage in volts.

Return Format:

Example:

FETC? returns 1.41000E+01, 3.00100E-00 (current is 14.1A and voltage is 3.001V).

B.6

MEASure:ADDRess? QUERY

MEAS:ADDR?

Syntax:

Short Form: MEAS:ADDR?

Long Form: MEASure:ADDRess?

Description:

Returns the address of the KLN in a format compatible with active interface (either RS-485
or GPIB).
When output is OFF, output voltage and current are shown as:

0.00000E+00,0.00000E+00 (0V, 0A).

Return Format: ,,, equivalent to

Address (preceded by “A” if RS 485),Output Voltage (volts), Output Current (amperes)

Example:

MEAS:ADDR? when using RS 485 with KLN 30-100 operating at rated output:

returns A007,3.00000E+01,1.00000E+02,
(address is 7, output voltage is 30V, output current is 100A

MEAS:ADDR? when using GPIB with KLN 30-100 operating at rated output:

returns 7,3.00000E+01,1.00000E+02
(address is 7, output voltage is 30V, output current is 100A

B.7

MEASure:CURRent? QUERY

MEAS:CURR?

Syntax:

Short Form: MEAS:CURR?

Long Form: MEAS:CURRent?

Description:

Returns 6 significant digits in floating format representing output current in amperes. The
number is two places more than shown on front panel Current display.

Return Format: (Current in amperes)

Example:

MEAS:CURR? returns 1.25024E+01 for output current of 12.5024A (front panel Current display
shows 12.50).

B.8

MEASure:VOLTage? QUERY

MEAS:VOLT?

Syntax:

Short Form: MEAS:VOLT?

Long Form: MEAS:VOLTage?

Description:

Returns 6 significant digits in floating format representing output voltage in volts. The num-
ber is two places more than shown on front panel Voltage display.

Return Format: (Voltage in volts)

Example:

MEAS:VOLT? returns 2.50057E+01 for output voltage of 25.0057V (front panel Voltage display
shows 25.00).
