3.1.12 LEVEL key and LED
In the dynamic mode of Constant Current mode, there is no any effect to the 33501
series load module although the LED can be indicated the High or Low level in the
Static mode. The only fact is switching the 33501 series load module from Dynamic
load to Static load; it can determine the load current is High or Low load current level.
In Static mode, the LEVEL key is used to program the High or Low level load current
in Constant Current mode, the High or Low load resistance value in Constant
Resistance mode, the High or Low voltage value in Constant Voltage mode, and the
High or Low power value in Constant Power mode.
.
3.1.13 PRES ON/OFF key and LED
At Preset OFF state, the load input voltage is shown on the upper 5 digit Meter, and
load input current is shown on the middle 5 digit Meter, the load input power is shown
on the lower 5 digit Meter, the engineering unit "V", "A" and "W" LED will be lit
respectively.
At Preset ON state, the PRES. LED is ON, the lower 5 digit Meter will be affected by
the CC, Dynamic, CR, CV, and CP operating mode.
In Preset ON condition, the 5 digit DCM indicates the setting load current which cab
be from front panel setting or remote system setting.
3.1.13.1 In Constant Current mode:
The High/Low level load current value can be preset at lower 5 digit LCD
display, the unit is "A", the "A" LED will be lit as well.
3.1.13.2 In Dynamic load mode:
The Thigh/Tlow parameters value of High/Low load current duration and
Rise/Fall setting can be displayed on the lower 5 digit LCD display, the unit
is "mS", the "mS" LED will be lit as well.
3.1.13.3 In Constant Resistance mode:
The High/Low level load resistance value can be preset on the lower 5 digit
LCD display, the engineering unit is "
Ω
", the "
Ω
" LED will be lit as well.
3.1.13.4 In Constant Voltage mode:
The High/Low level load voltage value can be preset on the upper 5 digit
LCD display, the unit is "V", the "V" LED will be lit as well.
3.1.13.5 In Constant Power mode:
The High/Low level load power value can be preset on the upper 5 digit
LCD display, the unit is "W", the "W" LED will be lit as well.
3.1.14 Limit key and LED
In the 33501 series electronic load module, the Limit key setting includes the GO/NG
check of Digital Voltage meter Upper/Lower limit, Current meter Upper/Lower limit,
and Watt meter Upper/Lower limit within the Limit key setting. The setting sequence
is shown below:
