40 K400 Issue No. 1
• CAL
Use the keys and pressing ent, changes the display. The new display allows
the setting of a temperature range to the specific voltage output of the device under
test.
Using the keys, move the cursor through this display and set the values with
the numeric key-pad: T min value is the low limit for the UUT temperature range,
related to its low limit output voltage, T max is the full-scale for the UUT temperature
range, related to the high limit of its output voltage. Press ent to confirm and to go
to the next display, where the error calculation mode can be set.
Using the keys, select ABSOLUTE and press ent: the final working screen
shows the generated temperature parameters in the bottom part of the display, and
the voltage measurement scaled into the selected temperature unit in the top part.
The error (deviation) calculation is shown with small digit between the two sections
of the display and with a temperature unit value.
If in the ERROR screen, using the keys, the % OF SPAN or % OF RDG
functions are selected, pressing the ent key, the final working screen shows the
error calculation as a percentage deviation related to the full-scale of the device
under test temperature range or to its specific measuring point.
