Introduction - Techne TECAL 700XS Manual Del Operador

InTroduCTIon

The Tecal 700XS is designed to provide an exceptionally stable and accurate heat source that can be used
in a calibration laboratory or a field environment. These units enable precise temperature calibration of
a wide range of temperature sensors and thermostats to be carried out. They offer fast heat up times,
with unrivalled accuracy and repeatability.
The Tecal 700XS accepts interchangeable insert probe sleeves allowing many sizes of probes to be
calibrated. The unit uses a PRT sensor and 4 specially manufactured heaters to achieve stable and uniform
temperatures throughout the block. The unit has a large fixed block with multiple bores accepting 5
different probe sizes as well as a separate bore for slim insert blocks to allow virtually any probe sizes to
be calibrated. The fixed aluminium bronze block offers improved thermal conduction across the block and
gives the flexibility of many probe sizes being catered for. Large removable insert blocks can give errors
due to the thermal breaks between the bore of the block and the clearance required to allow the insert
blocks' insertion and removal. This new design reduces these errors.
The all new control PCB features a large LED display allowing operating parameters including the block
temperature, block stability, heating status, and current set-point to be reviewed. The temperature can
be easily set using the control buttons to any desired temperature within the calibrator's specified range.
The 4 push buttons can also be easily used to perform switch test functions.
If the unit is used correctly this instrument will provide continued accurate calibration of temperature
sensors and devices in many applications.
The Tecal 700XS calibrator is designed to display the same temperature as the test sensor in the block. If
the unit is set to 700°C and the display reads 700°C and the calibration well is at 700°C.
Before using the Tecal 700XS make sure you have read this manual carefully. If there is any
doubt relating to the proper use of this equipment, the staff at Techne or your supplier will be
happy to assist.
