WARNING
Never use with toxic, corrosive, flammable or organic materials unless special
precautions are in place to prevent injury to personnel or damage to equipment.
WARNING
Never operate the appliance with the housing removed!
RISK OF FAILURE
Due to exceptional volumes of fluid expansion at elevated temperatures,
regularly check the fluid level in the bath!
DANGER
Temperature fluid expansion may cause overspill!
Adjust fluid level!
RISK OF FAILURE
Do not use rubber cap at elevated temperatures
DANGER OF BURNS
Use safety gloves when operating with high/low temperatures!
ELECTRIC HAZARD
Do not operate the equipment in wet and condensing environment!

2. INTRODUCTIONS
Calibration bath OBM was developed and manufactured specifically for the calibration of
temperature instruments, probes and liquid thermometers at temperatures from 35°C to
220°C. Fluid calibration baths ensure high temperature stability and uniformity across
working volume.
To ensure such specifications all calibration baths of our brand are designed with a special
double cylinder construction with uniform vertical flow in the working volume.
Of course, the construction is not enough that is why we are using high capacity
microprocessor controllers and different levels of heating.
Control panel with display is used to set the individual temperatures. All controllers are
also equipped with communication modules, so the appliance can be operated and
controlled via a PC.
Bath top, bath bottom and working chamber is completely made of stainless steel AISI 304,
which guarantees easy maintenance and long life time. Exterior housing is made of
aluminum sheets coated with high quality varnish.
WARNING
Temperature range must be limited / adjusted to reflect the properties of
the selected fluid!

1. Program: choose desire program number to edit settings (0- manual program, 1÷10 for automatic
program).
2. Steps: choose the required number of temperature steps (set range from 1to 10).
3. Stirring: choose speed for stirrer for fluid mixing (set range from 30% to 100%)
4. Auto Start: controller has option to set automatic start at certain hour and date (select YES or NO).
If you would like to start the program right after pressing the start button the auto start should be
set to NO.
5. Cycling: here you activate or deactivate cycling of steps (select YES or NO). If you would like to
work without cycling of steps then select NO.
6. Start Time: set the time for delayed automatic start (set range from 00:00 to 23:59 in hh:mm
format).
7. Start Date: set the date for delayed automatic start (set range ALL and 1to 31). The
number is day in month. If you set to ALL then all days in month are selected.
8. Cycles: set how many times the cycling of steps is repeated (set range from 1to 99).
9. Cycle from step: set the step number from which the cycling will start (set range from 1to
maximum 10 if we have 10 temperature steps). Cycling from step number must always be
bigger than Cycling to step number!
10. Cycle to step: set the step number to which the cycling will go (set range from 1to maximum
10 if we have 10 temperature steps) Cycling to step number must always be smaller than Cycling
from step number!
Example: “number of temperature steps” is set to 5, cycling of steps is set to 3, “cycle from
step” is 5, “cycle to step” is set to 1. So the program shall do 5 steps and then repeat them
for 3 times. Together we have 5 + 3 x 5 = 20. We have 20 steps to execute.
11. SETPT: set the setpoint temperature for current step (set range from 35.00°C to 220.00°C)
12. Dwell time: set the duration time of temperature stability for current step (set range from 00:01 to
24:00 in hh:mm format). For endless dwell time set time to 00:00. The countdown will start only
when temperature is within allowed tolerances from set values!
13. Ramp: set the speed how fast the temperature in bath changes (set range from 1°C/hr to 250°C/hr
(°C degrees per hour)). To activate speed ramp set mark ✓in rectangle.
Fluid mixing speed
After changing this parameter wait for a few
minutes for the system to stabilize!!!
Never change for more than a few % at a time!
