Operating Instructions with keypad input

4.4.1 Setting the limits

The voltage, current and power output values are each limited to a maximum. This
upper limit can be varied downwards. Setting the limits is carried out using the "V
LIMIT" "I LIMIT" "P LIMIT" keys as follows:
V LIMIT Voltage limit
Press the "V LIMIT" key in the "LIMITS" field until the symbol "U-const"
flashes. The voltage limit can now be adjusted to 1V steps by using the
encoder wheel. If the "V LIMIT " key is now pressed for longer than 2s,
the voltage upper limit will again be set at "maximum voltage value"
(40V). To complete the input, press the "ENTER" key. An inadvertently
wrong-set limit setting can be erased/reset with the " CE " key. As a
result of this, the previous set value will be indicated and the setting
menu exited. The "U-const" will no longer flash.
During operation, the voltage output can also be adjusted up to the set
limit.
I LIMIT Current limit
Press the " I LIMIT" key in the "LIMITS" field until the symbol "I-const"
flashes. The current limit can now be adjusted to 10mA ("FINE") or
100mA ("NORM", coarse) steps by using the encoder wheel. If the "I
LIMIT" key is now pressed for longer than 2s, the current upper limit will
again be set at "rmaximum current value" (5A). To complete the input,
press the "ENTER" key. An inadvertently wrong-set limit setting can be
erased/reset with the " CE " key. As a result of this, the previous set
value will be indicated and the setting menu exited. The "I-const" will no
longer flash.
