@ Display (7-segment LEDs)
Dualdisplaywith two 3-digit readoutsfor output voltage
and output current On the display on the left side of the
instrument the voltage and current readings for termi-
nals @ are indicated, The corresponding values for the
terminals @ are indicated on the right side of the dis-
play.
2 3 V/mA
Pushbutton for switching the display {left side wuth
right side with@) from voltage to current reading or Vice
versa. With the pushbuttons@or@depressed the cur-
rents supplied from the terminals@or@are
with a resolutionof I mA, With the pushbuttons@or@
released the voltage across the terminals 4 or 6 is dis-
played With a resolution of 0. V
@/@ Output O 20 V (4mm bananasockets)
Output terminals for 4 mm banana plugs or cable con.
nection. The output voltages are short circuit protected,
@ Output +5V (Fixed}
Output terminals for 4mm banana plugs or cable com
nection for the fixed +5V output, The output voltage is
short circuit protected by means of a

@ Output on
Pushbutton for switching off the 3 output voltages of
the HM 8040 simultaneously without switching off the
mainframe. The switch

excessive current
Overload indicators
Two LEDs for overload indication Of one Of the output
voltages e.g. current limiting or overheating. In case of
overheating or output currents in excess of the speci-
tied values the corresponding
