2. Verify system operating conditions:
a. At the Menu Panel, select Maint . , then select System Monitor .
Normal and abnormal indicators are listed below.
b. If there are abnormal indicators, take the appropriate corrective action.
NOTE: If you see an abnormal condition, check the Error Report window for more
information.

RRV Bath Temp.
Temperature status of the heating bath fluid
in the reaction tray. The normal temperature
range is 37.0
±
0.5
°
C. A temperature
exceeding 50
°
C with the thermostat on is
overheated.
OK
NG
Check the level of heating bath fluid and
replenish it, if needed.
RRV Bath Control
Circuit control that keeps the reaction
(RRV) bath temperature in range.
OK
NG
Check the level of bath oil and replenish,
if needed.
RRV Bath Circ.
Flow rate status of the heating bath fluid.
The status is determined by the flow rate in
the RRV Bath Circ. field.
OK NG
Make sure that there is a sufficient supply
of bath oil. If needed, add more oil to the
reaction bath oil bottle.
RRV Bath Circ. Rate
Flow rate of the heating bath fluid, in
mL/minute. A flow rate <2000 mL/minute
or >6000 mL/minute is considered
abnormal.
3000 -
5000
mL/min. <3000 or >5000 mL/min.
Fill the incubation bath oil bottle with
more oil. Adjust the flow regulator valve.
Make sure the bath oil is circulating
properly in the constant temperature bath.
RRV Oil Level
Status of the quantity of heating bath fluid.
Insufficient liquid is detected by liquid level
sensors in the bath. If insufficient liquid is
detected, more oil is pumped into the bath.
OK NG
Check the level of heating bath fluid and
replenish it, if needed.
Check the bath oil bottle.
Oil Bottle Level
Status of the quantity of heating bath fluid
in the bottle. Insufficient liquid is detected
by a liquid level sensor in the bottle.
OK NG
Fill the incubation bath oil bottle with
more oil. Make sure the liquid level
sensors are positioned correctly.
Wash vol.
Status of the water volume of the deionized
water bottle. Insufficient liquid is detected
by the deionized water bottle level sensor.
OK NG
Fill the pure-water (deionized) bottle.
Deionizers produce less water at colder
temperatures. If the temperature is lower
than normal, a supply problem may exist.
Also, check your exterior water supply to
confirm that it is adequately supplying the
internal water bottle.
