Description of the temperature step program
In this program, up to 6 different temperature steps can be programmed separate or together. Every single
temperature level can be set to any desired temperature within the operating range of the calibrator. The
resolution is 0.01 K.
The individual temperature levels are serially numbered from 1 to 6. If the "upward“ function is enabled, the
levels are approached in the order 1, 2, 3, 4, 5 and 6. If the "down“ function is enabled, the levels are
approached in the order 6, 5, 3, 4, 2 and 1. If the "upwards/down “ functions are enabled, the levels are
approached in the order 1, 2, 3, 4, 5, 6, 5, 4, 3, 2 and 1. In this case, disabled levels are skipped.
Using the
gradient
function, defined heating and cooling of the calibrator can be set. The value for the
gradient is set in KPM with a resolution of 0.01 K.
The upper level for the gradient is determined through the heating power of the respective calibrator. This
means that the calibrator with the gradient function enabled cannot heat at a faster rate than the calibrator
without the gradient function.
Using the
tolerance
and
time
the stability and length of the dwell time on a temperature level can be set. If the
dwell time is to be 5 minutes with a constancy of ±0.1 K after the temperature set point has been reached the
duration must be set to 5 min. and the tolerance to 0.1 K. In this case, the timer will start when the actual
temperature differs by less than 0.1 K from the temperature set point. If the temperature remains below this
tolerance for 5 min, the time period for the next level will be approached after the present time period has
elapsed. If fluctuations occur during this time that exceed the set tolerance, the timer is reset and restarted.
The tolerance can be set within the limits of 0.01 K and 5.00 K, the duration within the range of from 1 min to
100 min.
Using the cycles function the calibrator can approach the temperature levels continuously. If e.g. the
temperature levels 1, 2 and 3 are enabled and the "upward” function has been selected, the levels 1, 2 and 3
are approached one after the other depending on the set cycles: with a number of cycles of 3 this would be 1,
2, 3, 1, 2, 3, 1, 2 and 3. If the "upward” and "down” functions have been selected, the calibrator will proceed as
follows: 1, 2, 3, 2, 1, 2, 3, 2, 1, 2, 3, 2 and 1.
Attention!
While the temperature level program is enabled you cannot enable control mode using the control key. When
the level test mode is enabled the menu item "Switch test” in select mode is hidden and cannot be selected.
Probe Types
The probe types are not directly set in the "Select steps" submenu. Depending on the probe enabled in Select
mode, there are various options for the level test.
