How do I view/change the virtual model settings?
See PAR. 3.2.6 for description of virtual model.
If status shows SET, exit set-
point mode (tap either knob once).
Use thin tool to press FUNCTION once; status reads VIRT. VOLTS and AMPS displays show the
maximum voltage and current of the present virtual model.
If no change
, exit function mode (see above). To change, press DC OUT-
PUT once. Status shows PASS (password). Enter password
(see above)
and tap DC OUTPUT to accept. When password is
accepted, status reads VIRT, VOLTS and AMPS displays blink. To change setting rotate Voltage and Current knobs until VOLTS and
AMPS displays show desired virtual model settings. (Press and hold knob in while turning for fine adjustment.) Press DC OUTPUT to
accept virtual model settings. Unit displays DONE, then resets and repeats power on sequence.
How do I view/change overvoltage and overcurrent protection limits?
See PAR.3.2.6 for description of protection limits.
If status
reads SET, tap either knob to exit setpoint mode
. To view protection limits, use a thin tool to press and hold PROTECT until status
reads PROT, VOLTS and AMPS displays show the protection limits; to change limits, while continuing to hold PROTECT in, adjust
OVP and OCP limits using the Voltage and Current knobs. When PROTECT released, values showing in VOLTS and AMPS displays
are the new protection limits.
REMOTE ANALOG OPERATING MODE INSTRUCTIONS
How do I enable analog operating mode?
Connect ANALOG_CTRL (pin 12) to GROUND (pin 9, 11, 13, or 15) of analog port prior
to power-up to enable remote analog programming for that session. Remote analog control is indicated by "aREM" in status display.
The status of ANALOG_CTRL is sensed at power-up only
. Enabling analog operating mode disables the local operating controls on
the front panel. (see PAR. 3.4).
How do I enable or disable the output?
Connect REM_INH (pin 8) to GROUND (pin 9, 11, 13, or 15) of analog port to disable
power supply output, open the connection to enable the output (see PAR. 3.4.1). The DC OUTPUT control on the front panel remains
active in remote analog programming mode.
How do I adjust voltage and current setpoints using an external voltage source?
Set analog I/O DIP switch positions 1 and 2 up
(factory default position) to use external voltage control of voltage and current, respectively. Full-scale programming voltage is factory
set at 10V; to alter full-scale value see PAR. 3.2.13.6. Apply a 0-10V signal from Vref (pin 1) and Cref (pin 3) to GROUND (pin 9, 11,
13, or 15) of analog port to adjust the setpoint values for output voltage and current proportionally between minimum and maximum
virtual model limits.
Programming input pins are only active when analog port is enabled.
(See PAR. 3.4.3 for details.)
How do I adjust voltage and current setpoints using an external resistance?
Set analog I/O DIP switch positions 1 and 2 down
to use external resistance for remote analog programming of voltage and current, respectively. Full-scale programming resistance is
factory set at 10KOhms; to alter full-scale value see PAR. 3.2.13.6 and use 1000 ohms per volt scale factor. Apply a 0-10KOhm resis-
tance from Vref (pin 1) and Cref (pin 3) to GROUND (pin 9, 11, 13, or 15) of analog port to adjust the setpoint values for output volt-
age and current proportionally between minimum and maximum virtual model limits.
Programming inputs are only active when analog
port is enabled.
(See PAR. 3.4.2 for details.)
How do I Read back operating voltage and current?
Analog signals proportional to actual output voltage and current levels are
available at VOLT_RBACK (pin 6) and CURR_RBACK (pin 7) of analog I/O port. Full-scale signal level is the same as that for full
scale programming. Readback signals are always available at analog port, even if analog programming is not enabled.
How do I exit remote analog programming mode?
Simultaneously depressing and releasing both Voltage and Current knobs
forces the unit to exit remote analog programming mode and return to local operating mode; this can also be done by sending any
command or query via the remote digital inputs. To restore remote analog control cycle source power OFF for five seconds then
restart.
REMOTE DIGITAL OPERATING MODE INSTRUCTIONS
How do I enable digital operating mode?
Sending any digital command or query via either the GPIB, LAN or RS 232 port immedi-
ately sets the unit in remote digital operating mode and disables the local operating controls on the front panel. For details on com-
mand formatting and communication protocols see PAR. 3.3.
How do I exit remote digital programming mode?
Simultaneously depressing and releasing both Voltage and Current knobs will
force the unit to exit remote digital programming mode and return to local operating mode. Remote digital control is reactivated upon
transmission of any digital command or query by the control (host) computer.
How do I view/change the GPIB address?
The factory default GPIB address is 6. Using a thin tool, press FUNCTION once; status
reads VIRT. Rotate Voltage or Current knob until status reads ADDR; the active GPIB address shows in AMPS display. To exit,
rotate Voltage or Current knob till status reads EXIT then tap DC OUTPUT. To change, tap DC OUTPUT: AMPS display blinks.
Rotate Current knob to change address and tap DC OUTPUT to accept; display flashes DONE then ADDR. See above to exit.
How do I view/change RS 232 baud rate? [-1200 Models Only]
The factory default RS 232 baud rate is 38400. Using a thin tool,
press FUNCTION once; status reads VIRT. Rotate Voltage or Current knob until status reads BAUD; AMPS display shows active
baud rate x 1000 (e.g., 38400 is displayed as 38.4). To exit, rotate Voltage or Current knob till status reads EXIT then tap DC OUT-
PUT. To change, tap DC OUTPUT: AMPS display blinks. Rotate Current knob to change baud rate and tap DC OUTPUT to accept;
display flashes DONE then BAUD. See above to exit. See PAR. 3.3.1.2 for additional RS 232 parameters.
How do I set up the LAN interface?
[-1.2K Models Only]
See PAR. 3.2.12 and refer to KLP Developer’s Guide.
How do I operate the KLP using web pages via the LAN interface?
[-1.2K Models Only]
See PAR. 3.3.6 and refer to KLP Devel-
oper’s Guide. Use the PSfind program (on CD supplied) to locate KLP(s) functioning on the LAN. Highlight the unit and click Launch
Web Page. Click OPERATE INSTRUMENT. Simulated front panel shows status of voltage, current, output on/off, and operating
mode (CV or CC). Operating functions supported from Operate Instrument page: Set output on/off and output voltage/current (PAR.
3.3.6.5.1), overvoltage/overcurrent protection (PAR. 3.3.6.5.2), save/recall (PAR. 3.3.6.5.3), reset (PAR. 3.3.6.5.4), list (PAR.
3.3.6.5.5) and virtual model (PAR. 3.3.6.5.6). Click CONFIGURE LAN to change LAN addresses or set up LAN passwords (PAR.
3.3.6.3). Click ID INSTRUMENT to flash physical LAN indicator on KLP.
