1."R" type thermocouple for controlling and
over temperature protection.
Inner chamber of calsys 1500L
5.1 Power
Place the calibrator on a flat surface with at least 20 inches of free space around the instrument.
Overhead clearance is required. Do not place under a cabinet or structure. Insert equilizing block
into the well with help of tong, after inserting remove the tong from equalizing block. Plug the
power cord into mains outlet of the proper voltage, frequency Typically this will be (230 VAC ±10,
50/60 Hz). Turn the “Mains” (Heater) switch located on front panel. The controller dispaly should
illuminate after 3-4 sec . After a brief self test the controller should begin normal operation. If the
unit fails to operate please check the power connection.
[!]Warning: Do not connect or disconnect while power is on. Do not disconnect
power when furnace is hot and fans are running.
5.2 Setting the Temperature
Press “UP” or “DOWN” buttons to change the change the temperature set-point value. When the
set-point temperature is changed the controller will switch the CALsys 1500 L ON or OFF to raise or
lower the temperature. The displayed temperature will gradually change until it reaches the setpoint
temperature. The temperature bath requires 15 to 20 minutes to reach the set-point depending on
the span. Another 10 to 15 minutes is required to stabilize the temperature bath within ± 0.5ºC of
the set-point.
5.3 Operating Instruction:-
1.
Insert the ceramic block (thermowell) into well of furnace. Block should be face to face of inner
chamber.
2.
Connect the ‘CALsys 1500L’ to a suitable power supply & Switch ON the Dry bath source and set
the desire temperature value in PID by using UP & Down key.
3.
Switch ON the MCB,back side of furnace.
4. Insert the reference (Master) temperature sensor and UUC (Unit under calibration) into the
thermowell (inconel block).
5.
PV (Present value) display in controller will gradually rise until it reaches the set point
temperature. The controller takes some times to reach the set-point depending on the span.
Furnace is stable when PV is equal to SV (Set Value).
Note:
All other controller parameters are company set and locked. It is
recommended not to change them.
When the source is operated at any temperature above ambient,
the front face and plate become hot. UP
