3.2.12. key and LED
The LEVEL button is used to program a High or Low load value. The setting value
Changes between current, resistance, voltage or power depending whether CC, CR,
CV or CP mode has been selected. If the LED is lit then the High level value setting
Has been enabled. If the LED is not lit then the low load level can be set using the
Rotary switch in combination with the arrow keys.
In STATIC mode the user can switch between High and low load levels during
Operation.
In DYNAMIC operation (CC & CP modes only) the preset high and low levels are
Used to define the dynamic waveform.
Please note that the low level setting cannot exceed the high level. The converse is
Also true in that the High level cannot be set below the low level.
3.2.12.1 In Constant Current mode:
The level is initial setting on High, LEVEL High / Low has two level, Low
Current level setting must be lower than Level High.
3.2.12.2 In Constant Resistance mode:
The level is initial setting on High, LEVEL High / Low has two level, Low
Resistance level setting must be lower than Level High.
P.S.：CR Mode Level High / Low level by current perspectives.
3.2.12.3 In Constant Voltage mode:
IF Low level load voltage value greater than High level load voltage value
or opposite status，the load voltage value is equal.
P.S.：CV Mode Level High / Low has "automatic push function".
3.2.12.4 In Constant Power mode:
The level is initial setting on High, LEVEL High / Low has two level, Low
Power level setting must be lower than Level High.
P.S Automatically Push Function
Level setting, Level High must be higher or equal than Level Low; When
Level High equal to than LEVEL Low, it can not be adjusted anymore.
when Level High equals to lower low, the Automatic push function can push
down the level Low value.
Therefore, the Level High can continue adjusting.
3.2.13. Key and LED
If the PRESET key is pressed the button will become lit indicating that the PRESET
mode has been accessed. The lowest 5 digit display will change from showing the
power consumption in watts to displaying the value to be preset. The value that
can be programmed changes according to the operating mode that has been
selected
