7. Temperature Mode
The temperature readout must be calibrated before attempting calibration of any of the other readout
modes.
A “
∗
” in place of the decimal point indicates that the Temperature readout is not calibrated, or a
past calibration has failed. The “
∗
” will be removed once Temperature has been successfully
calibrated.
The
smart
CHEM
-C
is able to take Temperature readings from the Temperature sensor or from the
Conductivity/TDS sensor. If both the Temperature sensor and a Conductivity/TDS sensor are
connected at the same time, the Temperature reading is taken from the Temperature sensor.
7.1 Temperature Calibration
1. To calibrate the separate Temperature sensor, plug the temperature sensor into the
Temperature
socket.
To calibrate the Temperature readout from a Conductivity/TDS sensor, plug the
Conductivity/TDS sensor into the
Cond / TDS
socket and ensure that the separate
Temperature is not connected.
2. Switch the meter on.
3. Place the Temperature or Conductivity/TDS sensor into a beaker of room temperature water,
alongside a good quality mercury thermometer. Stir the probe and the thermometer gently to
ensure an even temperature throughout the beaker.
4. Select Temperature Calibration (

→
F1:Calibrate
→
→
F3:Temperature
).
The Temperature Calibration screen is now displayed. The bottom line provides confirmation
of which sensor is being calibrated. The following example shows the Temperature sensor
being calibrated.

The current reading from the Temperature or Conductivity/TDS sensor is displayed.
5. Type in the temperature as measured by the mercury thermometer using the Numeric Keypad
and press
. The Automatic Stability Function will now show a and highlight the
Temperature reading while it is unstable…

Waiting to Stabilise
When the Temperature reading has stabilised, the unit will calibrate itself.
To calibrate immediately without waiting for complete stability, press
to disable the
Automatic Stability Function.
6. The
smart
CHEM
-C
is now calibrated for Temperature and is ready for use in this mode.
