Setting the Temperature

Section 8.2 explains in detail how to set the temperature set-point on the
calibrator using the front panel keys. The procedure is summarized here.
1. Press the "SET" button twice to access the set-point value.
2. Press the "UP" or "DOWN" button to change the set-point value.
3. Press the "SET" button to program in the new set-point.
4. Press the "EXIT" button to return to the temperature display.
When the set-point temperature is changed the controller switches the
heater on or off to raise or lower the temperature. The displayed tempera-
ture gradually changes until it reaches the set-point temperature. The tar-
get may require 5 to 10 minutes to reach the set-point depending on the
span. Another 5 to 10 minutes is required to stabilize within ±0.1°C of the
set-point. Ultimate stability may take 15 to 20 minutes more of stabilization
time.
