requirements. Turn the calibrator on using the “POWER” switch on the power
entry module (PEM). The calibrator will turn on and begin to heat or cool to
the previously programmed temperature set-point. The front panel LED dis-
plays will indicate the actual calibrator temperature.
4.4 Setting the Temperature
Section 7.2 explains in detail how to set the temperature set-point on the cali-
brator using the front panel keys. The procedure is summarized here.
(1) Press “SET” twice to access the set-point value.
(2) Press “UP” or “DOWN” to change the set-point value.
(3) Press “SET” to store the new set-point.
(4) Press “EXIT” to return to the temperature display.
When the set-point temperature is changed the controller will switch the well
heater on or off to raise or lower the temperature. The displayed well tempera-
ture will gradually change until it reaches the set-point temperature. The well
may require 5 to 10 minutes to reach the set-point depending on the span. An-
other 5 to 10 minutes is required to stabilize within ±0.1°C of the set-point. Ul-
timate stability may take 15 to 20 minutes more of stabilization time.
4.5 Changing Display Units
The 9009 can display temperature in Celsius or Fahrenheit. The instrument is
shipped from the factory set to Celsius. To change to Fahrenheit or back to Cel-
sius perform the following:
1. Press the “SET” and “UP” button simultaneously. The temperature displays
the converted temperature and units.
Or
1. Press the “SET” button three times.
2. Press the “UP” or “DOWN” buttons to change the units.
