Ramp Mode:
(Not available in P to V / mA mode)
Ramp mode consists of two parts, a ramp and level. The
'Step' and 'Range' (zero and full scale) determine the values
for voltage / current at each of the levels (see Fig.4).
Rate is the Ramp rate or increments in V/sec or mA/sec.
Dwell_time is the time for which the output (source) stays on
each level, when the Dwell_time has expired the output will
ramp to the next level.
With the Ramp status on, the unit will operate in Ramp
Mode, with the Ramp status off, the unit will operate in Step
Mode ( using the same steps as the Ramp Mode but with no
ramping between levels). In Step Mode, pressing the
or
key will cause the output to increase or decrease to
the next level. In Ramp Mode, the
ramping, the
key will return the unit to Measure Mode.
Pressing the
Ramp Mode to its starting point. In Step Mode, pressing the
Keys together returns to the first Step level.
To enter 'Nudge Mode' (where the output increments in
smaller steps) press and hold down the
seconds (operates in source 'Step Mode' only). The unit will
bleep to indicate that the Nudge Mode has been activated.
In Nudge Mode the source symbol changes to either
depending upon the nudge direction. To exit from

mA range = 1uA
Lower V range = 0.2mV (up to 5.5V)
Upper V range = 2mV (5.5 to 10V)
