Multiple Oprations
Up to two HP 6038A units may be connected in series or
auto-parallel, to provide increased output capabilities. Note
mixing supplies with dis-similar output capabilities is not
recommended; because under certain conditions, the lower
output unit may be stressed beyond it's maximum voltage
and/or current capabilities by the higher output unit.
Overvoltage Protection
Trip voltage adjustable via front panel control.

function}
TC: 100 ppm +5 mV/°C
Minimum setting above output voltage to avoid nuisance
tripping is 1.5 V.
Remote Analog Programming (25 ±5 ''O
Resistance programming:
0 to 4 k provides zero to maximum rated output voltage or
current. The resulting scale factor is 1 ohm/LSBfora 12-bit
system, which corresponds to 2(X) ohms/volt and 133
ohms/amp.
Voltage:
Accuracy: 0.42% 4-30 mV
TC; 50 ppm 4 3 mV
Current:
Accuracy: 0.8% 420 mA
TC: 100 ppm 4 0.3 mA
Voltage programming:
0 to 5 V provides zero to maximum rated output voltage or
current.
Voltage:
Accuracy: 0.25% 4 30 mV
TC: 10 ppm 43 mV
Current:
Accuracy: 0.15% 420 mA
TC: 70 ppm 40.3 mA
The programming inputs are protected against input voltages
up to ±40 V.
