2.3 PAUSE FUNCTION
The normal pause function operates as follows:
During a scan the scan stops but the iontophoresis continues at its set current.
During the interval between scans the iontophoresis continues at its set current.
Pause can be used to manually alter the iontophoresis duration and scan interval.
There is a timer at the bottom left of the screen. This continues to count down the time remaining of
the total scan interval and then counts up the
extra
time caused by the Pause function.
Pause can be useful to allow extra temperature equilibration time after filling an ion chamber when
dry and wet skin baseline measurements are required.
The effect of a pause is shown below.
2.4 MANUAL IONTOPHORESIS
This is intended for use only when periods are required unrelated to scan interval. The baseline
recording and response recordings can only be made in separate single scan and or repeat scan
window. It cannot be used during an interval within a repeat scan.
To iontophorese using this mode select
Ionto, Manual Control
The
Iontophoresis
Cuurent
window will then allow
Current
and its
Duration
to be set.
To start the iontophoresis current click on
Set
and at the end of iontophoresis click on
Close
.
A scan cannot be started until this window is closed.
