Chapter 4 Operation
1. Temperature and time setting
a) Press the On/Off switch to power on the
instrument. The instrument performs a self
test followed by an alarm to signal that the
product is ready for use.
b) After about 3 sec. the temperature will
automatically increase to the most recent
setting. The values shown on the display
are actual settings (real time temperature &
time remaining.) The example shows an
actual temp. of 28.5°C and 35 min. remaining.
c) To adjust the set temperature,use the and
keys to selectl the desired temperature (Ex.
55.5). After 5 seconds, the temperature is
stored and the instrumnent will begin heating.
d) To set the time, Press the “Mode” key, the
displayed time begins flashing, press or
keys to set the desired time (ex. 1 hr 20 min.).
After 5 seconds the desired time is stored.
NOTE: The timer will not begin unless the
“Start/Stop” button has been pressed

2. Timer Operation (Advanced)
The default setting of the instrument is designed so that the heater will continue to hold
the set temperature even once time has expired and “oVEr” is showing on the time display.
This setting can be adjusted so that the heater will shut down once time has expired. To
adjust the advanced timer setting pres the “Mode” key and hold it for 10 seconds. After
10 seconds, the display will show “OP:1” use the or key to select “OP:2”. The
setting has now been changed and can be stored by pressing the “Start/Stop” key.
3. Temperature Calibration
The temperature of the instrument has been calibrated prior to shipment from the
factory. However, in the event that an adjustemnt to the calibration is required, the
user can adjust the calibration with either a thermometer/thermocouple or with the
optional external temperature probe. (sold separately).
Caution: the instrument uses double temperatures adjustment to ensure accuracy over
a wide range of temperature. It is linearly adjusted at both 40° and 100°C.
a) Calibration with a thermometer:
BSH5000 Operation manual Chapter 4 Operation Guide

a) Power on the machine and ensure that the temperature on the display is less than
35°C.
b) Inject olefin oil into one of the cone-shaped wells, and then put a
thermometer/thermocouple into this well (make sure that the precision of the
thermometer should be within 0.1℃and the temperature ball should be absolutely
immerged into the cone-shaped well). See Fig a.
c) Press “Mode” key without releasing, then press key
at the same time and hold for 3 seconds, it will enter into
the temperature calibration interface, see the right.
At this point, “ ” displayed, which indicates entering
into temperature calibration program. The temperature
displayed is current temperature and begins to rise to
40.0° automatically.
When the temperature reaches to 40° and is able to hold
a constant temperature, the decimal digit begins to flicker.
After 20 minutes, the user can read the value on the
Thermometer and use the up and down keys to enter the
value of the thermometer.
Notes: Please read the actual value after 20 minutes’ constant

temperature to ensure the calibration accuracy.
If the actual read out of thermometer is 39.6, modify the
temperature to 39.6 by pressing or . Then press “Start/Stop”
to confirm the input value.
d) Then the instruments will the automatically begin to heat to 100℃. Once 100C is
reched and held as constact, the decimal begins to flicker. After 20 minutes, the
user can read the actual value from thermometer.
Notes: Please read the actual value after 20 minutes’ constant temperature to ensure
the calibration accuracy.
If the actual readout is 101.5, modify the temperature display
to 101.5 by pressing or . Then press “Start/Stop” to confirm
the input value.
Note: Pressing “Set” and “” simultaneously during the temperature calibration
indicates exiting the temperature calibration program. The adjustments will be
cancelled and the changed value will be of no effect.
3.2. Calibration with the External sensor:
a) Power on the machine and ensure that the temperature on the display is less than
35°C.
b) Put External sensor into a block well.
c) Press “Mode” key without releasing, press “Start/Stop” key
and hold for 3 seconds, it will enter into temperature
calibration interface, see the right. At this point, “ ”
displayed, which indicates entering into external temperature
calibration program. The temperature displayed is External
sensor’s current temperature and it begins to rise to 40.0°
automatically.
It will automatically display “ ” six seconds later.
