from the system.
4 Place the disintegration beaker(s) through the holes in the top cover
of the water bath.
5 As the water circulates, there may be a slight drop in the water bath
level as the internal tubing fills. Wait until the beakers are in place
before adding additional water as required to bring the level back to
within no more than 2.5 inches of the top of the water bath. Replace
the cover, if removed.
Installing the Temperature Probe
The 100 is shipped with a factory-installed temperature probe inside the
heater /circulator tank and an external probe to be placed directly in the
water bath. Both probes are necessary and the temperature readings
must remain within 5 °C of each other or the 100 will not operate. If
either probe is not functioning or not installed, the alarm sounds and the
keypad is inactive.
To install the external temperature probe, complete the following steps:
1 Plug the temperature probe into the jack labelled TEMP. PROBE on
the rear panel.
2 Insert the metal tip of the probe into the small hole in the water bath
cover.
3 Ensure the small hole and temperature probe are toward the front of
the water bath.
NOTE
Check for leaks. Allow the circulator to run for five minutes, then check
the bath, tubing, connectors and the bench area immediately
surrounding the apparatus. If any water leaks are seen, turn off the
power immediately and remove the power cord. Locate and fix the
source of the leak before proceeding.
NOTE
No installation or positioning is necessary for the internal temperature
probe.
