Measurements and related features
Relative Humidity / Temperature Probe Measurements
1. Connect the supplied Relative Humidity/Temperature Probe to the meter as previously
described.
2. Press and hold the FUNCTION button until the ‘RH’ display icon appears and then release the
button.
3. The LCD display will now show the RH reading in % on the top of the display and the
Temperature reading (measured by the probe NOT the thermocouple) displayed on the bottom
in
o
C or
o
F (use the Setup Mode to change the unit of measure).
4. Dashes are displayed if the supplied Probe is not connected or if the reading is out of range.
5. Note that RH readings require a longer stabilization time to settle than Temperature readings.
Type J/K Thermocouple Measurements
The SDL500 accepts an optional Type ‘J’ or Type ‘K’ Thermocouple Temperature sensor.
1. Connect a thermocouple to the sub-miniature jack at the top left of the meter labeled
‘Thermocouple Temp. Probe’.
2. Press and hold the FUNCTION button until the ‘TP’ display icon appears. Release the button
when this ‘TP’ display icon appears. This allows the user to view the thermocouple reading in
o
C
or
o
F. The thermocouple type (‘J’ or K’) is also displayed.
3. Use the Setup Mode to change the unit of measure and thermocouple type and to further
configure the meter. Refer to the Setup Mode section below.
IMPORTANT SAFETY NOTE: The SDL500 can measure and display temperature up to 1300
o
C
(2372
o
F), however, thermocouple ratings vary widely; ensure that the thermocouple being used
is rated accordingly for the temperature being measured.
If an attempt is made to measure temperatures higher than the thermocouple’s rating, damage
to the thermocouple and the meter can result. If measurements are attempted outside of the
rated measurement range of a thermocouple personal injury is also possible.
Dew Point Temperature Calculation Display
The SDL500 can display the results of a Dew Point calculation based on Relative Humidity and
Temperature measurements.
Follow the instructions for the ‘Relative Humidity /Temperature Probe Measurements’ section
above, but release the FUNCTION key when the ‘dP’ icon appears. The display will now show the
Dew Point Temperature.
