Typical Constant Current Operation - BK Precision 1760A Manual De Instruccion

Typical Constant Current Operation

1. Before connecting the device to be powered to the power supply,
determine the maximum safe voltage to be applied, set the meter
selection switch to the V position, and set the VOLTAGE
controls to obtain that voltage reading on the LED display.
2. Determine the desired constant current value.
3. Set the CURRENT control to minimum (fully counterclockwise).
4. Turn off the power supply and connect it to the device to be
powered.
5. Turn on the power supply. The CC indicator should light if the
load is greater than 5% of full scale.
The CC indicator will not light if the load is less than 5% of
full scale or approximately 0.1A.
6. Set the meter selection switch to the A position to obtain the
current metering mode.
7. Increase the CURRENT control setting until the desired constant
current value is read on the display, or set the current limit in
advance (before connecting the load) as prescribed earlier in the
"Setting Current Limit" procedure.
8. If the load current drops below the constant current value, the CC
indicator will go off and the C V indicator will light. In this case,
the power supply automatically switches to the constant voltage
mode, and further rotation of the CURRENT control will not
increase the output current.
