BM/BO series units feature a built-in safety device to automatically prevent overheating, plus a thermal
fuse for redundancy.
How overheating prevention devices work:
The main overheat prevention device is set to activate at temperature setting plus 40°C, at which point power
is cut and Error 6 is displayed. Recovery takes place when the source of overheat is eliminated and the unit
is restarted by turning the main power switch off and back on. The thermal fuse is set to break at 128°C (for
BM500 and 510 models) or 192°C (for BO400 and 410 models), cutting power to the heater.
Caution:
●
If hot water is added during operation, bringing temperature to 40°C or more beyond
temperature setting, the unit interprets this as an overheating event. Power is cut to the
heater, and error 6 is displayed. If bath water level becomes too low while unit is running,
cancel operation before adding.
●
If overheating prevention devices activate outside of the above parameters, unit may be
faulty. Turn OFF main power switch immediately, disconnect the power cable and call for
service.
●
Overheating prevention functions are to prevent abnormal overheating and protect BM/BO
unit. They are NOT intended as test sample or specimen protection measures, nor are
they intended as prevention against accidents resulting from the negligent use of this
product.
Power failures.
When a power failure occurs, BM/BO units stop and keep operation in standby to maintain safety.
Press and hold START/STOP to re-start the operation.
Select [on] under [Pon] (power loss recovery) in the
MAINTENANCE menu for automatic operation recovery. Do not
leave unit unattended when unit has been set to continue
operation after a power loss. (See P.28)

Set Calibration Offset
The offset function works to correct discrepancies found between the
bath temperature reading, as seen on the display and actual bath
temperature, as taken manually, by matching temperature setting to the
actual temperature. Enter a positive difference value when the bath
temperature is found to be higher than the control panel reading. Enter
a negative difference value when bath temperature is found to be lower
than the control panel reading. Use the MAINTENANCE menu to set
or cancel this function. The factory default calibration offset value is
[0]
① Start a constant temperature operation at any temperature. When
temperature stabilizes, measure bath temperature using a
temperature recorder or other precision thermometer.
② If control panel temperature reading and manually taken temperature
differ, follow the steps below:
③ Press and hold TIMER for about four seconds, then press it
repeatedly until [cAL] is displayed.
④ The screen displays [cAL] and correction temperature. Enter the
difference (negative or positive) using △▽ while digits are flashing.
This completes the setting.
If a negative value is entered, bath temperature rises according to the
value entered. If a positive value is entered, bath temperature
decreases by the value entered.
Example:
A temperature reading of 60°C and an actual temperature of 58°C
would call for an offset value of -2, bringing the actual temperature up
2°C, to 60°C.
