3.2.6. Output current setting
The output current may be set immediately as a potentiometer “SET CURRENT” or first pre-set
“SET CURRENTd” and thereafter accepted with the ”” key. Set the output current by choosing
the “SET CURRENT” menu, position the cursor above the digit to alter and adjust the digit with
the “” or “” keys.
When the output current is within a predefined limit of the set value, the "READY" LED will turn
ON.
It is also possible to set the output current to a predefined value, either using the storage
registers (STO, RCL in the MEM menu), to maximum current (=100%) or to zero (=0%).
The maximum allowed set value can be limited through the LIMITS menu. Separate limits can
be set for the positive and the negative set values. If it is not possible to adjust the current
above a certain value, then check the limits.
Note: The storage and the limit registers are saved within the M-Panel and therefore cannot
be used in remote control. When using multidrop configuration e.g. all power supplies
will share the same limit.
3.2.7. Polarity reversal (Optional)
If a polarity reversal switch is installed, a sign will be shown in front of the set value (+ is NOT
reversed). A polarity change can be initiated through the “POL”-menu or by changing the sign
of the set current. In case of a polarity change, the MPS will ramp down the current and wait
for it to reach zero. Then a change pulse is sent to the polarity switch to initiate the polarity
change. When the completion of the reversal is detected, the current is ramped up to the set
value again.
