4 OPERATION
4.1 CONTROLS
There are four control switches arranged around the display screen. Operate the
switches by touching one end of the actuator onto the glass in the marked area.
Keep the actuator in position until you see a change in the display or the flashing
indicator.
The two top switches are used for the main control functions. They take a few
seconds to operate so that there is less chance of any accidental actions.
4.2 I/O SWITCH
The top left switch is the I/O (on/off) switch. Switch the instrument on by
activating this switch. Switch the instrument off by activating and holding this
switch for at least ten seconds. The display shows you what is happening.
Remove the actuator after the instrument switches off.
If there are any recorded files they will be saved during the time the instrument is
switched off.
You cannot switch the instrument off when the battery is charging from a Redpost
printer/charger unit or a Redpost battery charger.
4.3 INDICATOR
The small green lamp on the panel flashes once per second to show that the
instrument is operating. This lamp also flashes quickly five times to acknowledge
the action of either of the two top switches.

4.4 DISPLAY ILLUMINATION
The I/O (on/off) switch also turns on the backlight that lights up the display.
When any switch is operated or there is any other activity, such as connecting a
probe, the backlight will turn on. It will turn off again after a short time to save
battery power. Activate the I/O switch (for about half a second) to turn on the
backlight without causing any other action.
If there is very little charge in the battery then the backlight will not turn on. This
saves unnecessary battery drain.
4.5 SWITCH FUNCTIONS AND ICONS
The I/O (on/off) switch always keeps the same function but for the other three
switches the display will show a small “icon” to indicate the function of each
switch. The icon is in the same corner as the switch it relates to. The switch icon
becomes inverted (black for white) when the switch is operated. If a switch has
no icon then it has no function at that time.
4.6 AUTO POWER ON
The instrument will automatically switch on when it is connected to a Redpost
printer/charger or a Redpost battery charger. This allows the battery charging to
be controlled and the charging information to be displayed.
The I/O (on/off) switch will not turn the instrument off while it is connected to a
charger but it can still be used to turn on the display backlight.
4.7 AUTO POWER OFF
The instrument uses several methods to reduce battery power consumption. The
automatic control of the display backlight is described above.
If the instrument is idle and waiting to record a file it will automatically switch off
after ten minutes. The instrument is idle if no switches are activated, no data
communication is taking place and it is not connected to an active battery
charger.
If the instrument is idle and displaying the results of a recorded file it will
automatically switch off after twenty minutes.
When the instrument switches off automatically any recorded files are saved.
To resume normal operation activate the I/O (on/off) switch or connect the
instrument to a Redpost battery charger.

4.8 LOW BATTERY CONDITION
If recording is taking place when the battery charge level falls below 15%
then recording will stop and the file will be saved. This ensures that
recordings cannot be corrupted by low battery condition. The results
screen will show the reason for stopping.
If there is less than 15% charge in the battery then the backlight cannot be
switched on. This helps to ensure that the battery lasts for as long as
possible. The backlight increases the battery drain by about four times.
At an even lower level of charge (below 5%) the whole instrument will turn
off. Any recorded files will be saved. If you switch the instrument on again
in this state it will stay on for only a few seconds. Connect the instrument
to a Redpost battery charger as soon as possible.
The instrument continuously monitors its own battery use and battery
charging to gauge the amount of charge that remains in the battery. If the
battery voltage falls to a low level unexpectedly it may indicate that the
battery is not correctly holding its charge. This can happen after several
years of use. If this problem occurs the display will warn you that the
battery may need to be replaced. More information can be found in the
“Maintenance” section.

5 STARTING
5.1 PREPARING THE INSTRUMENT
Switch on the instrument. If there are any problems, such as insufficient charge in the battery,
the display will give the information you need. Before the temperature probes are connected
the location and numbering of the sockets is shown on the display.
Set up the bottle or can in the correct size holder and fit the correct length temperature probe.
Connect this probe into the channel 1 socket. Channel 1 is to the right of the display. When
calculating the results channel 1 is given most importance and is assumed to show the product
temperature.
Select the spray probe or second container temperature probe and connect it to channel 2.
Channel 2 is to the left of the display.
Both sockets must always be occupied. To run without one of the probes you can connect a
dummy temperature probe. (A special plug marked with a ‘T’.) You can also configure a
channel to be permanently inactive: see the section “Key Plug”. An inactive channel is shown
by an X on the screen.

Only for RPU-353:
In order to make a record run the pressure sensor can be connected in the same bottle as the
temperature sensor.
Preparation for measurement in bottles and cans. For bottles an additional centre ring (1) is
needed to centre the bottle. Preparations are:
1. Adjust the Piercing mechanism (2) by placing a sufficient amount of distance tubes
Bottle length = 80 (base ring) + n x 40 (distance ring) + n x 5 (distance ring)
2. Tighten nut (3).
3. Place bottleor can on the base (4)
4. Lower the plate with pressure adapter and temperature sensor (5).
5. Close the piercing mechanism (2)
6. Optional snifting. By pushing the levers (2) up and down quickly, the pressure in the
bottle or can gets down to the atmospheric pressure
7. Push the temperature sensor (6) down into the bottle and adjust the sensor with the
screw (7). This process is described in the section “Appendix 1: Background Information”
