Operation Sorensen SLH-Series DC High Power Electronic Load
5. Select the desired CR level by pressing the LEVEL key (9). When the LED is lit, the
HIGH level (lower resistance) is selected and when unlit, the LOW level is selected
(higher resistance).
6. Press the LOAD key (8) to toggle the load off or on. The LEVEL key can be pressed
at any time to switch between the settings. The current can be changed at any time
using the inc/dec arrows. The value set can be viewed by pressing the PRES key.
CV Mode
CV mode operates in static mode only. Two levels can be set to allow for quick switching
between two current levels.
1. Press the MODE key (3) until the CV LED (3) is lit.
2. Press the PRES key (7) to view the programmed values. The high level must be
higher than the low level; in setting the values, the load will not allow the HIGH level
to be lower than the LOW level.
a. To set the high level, press the HIGH key (16) in the lower part of the settings
area. Use the inc/dec arrows to set the desired level.
b. To set the low level, press the LOW key (16) at the bottom of the settings area.
Use the inc/dec arrows to set the desired level.
3. To exit the preset mode, press the PRES key until the LED is green (power/watts
displayed) or not lit.
4. Select the desired level CV mode by pressing the LEVEL key where LED lit is high
level and unlit is the low level setting.
5. Press the LOAD key to toggle the load off or on. The LEVEL key can be pressed at
any time to switch between the settings. The current can be changed at any time
using the inc/dec arrows. The value set can be viewed by pressing the PRES key.
CP Mode
CP mode can be either static (fixed DC level) or dynamic (two levels with timing and current
slew rates programmed). Dynamic mode is described in Section 0. In static mode, two
levels can be set to allow for quick switching between two current levels.
1. Press the MODE key (3), until the CP LED (3) is lit.
2. Press the PRES key (7) to view the programmed values. The high level must be
higher than the low level; in setting the values below, the load will not allow the HIGH
level to be lower than the LOW level.
a. To set the high level, press the HIGH key in the lower part of the settings area.
Use the inc/dec arrows to set the desired level.
b. To set the low level, press the LOW key in the lower part of the settings area.
Use the inc/dec arrows to set the desired level.
3. To exit the preset mode, press the PRES key until the LED is green (power/watts
displayed) or not lit.
4. Select the desired level CP mode by pressing the LEVEL key. When the LED is lit,
the high level is selected; when the LED is not lit, low level is selected.
