SC-1
After a calibration, METER recommends verifying that a calibration was effective.
1. Navigate to the Measurement tab.
2. Press ENTER to take a measurement on the calibration plate.
NOTE: If possible, do not wet the filter paper again for the verification readings. If wetting is necessary, disregard
the first measurement taken.
3. Repeat two to three times.
The measured conductance should be close to 240 mmol/(m
2
s).
4.2 MAINTENANCE
The SC-1 may be returned to METER for maintenance in the following areas: system
inspection, parts replacement, and instrument cleaning. Replacement parts can also be
ordered from METER. Contact Customer Support for more information.
The SC-1 should be kept clean with full batteries to ensure proper working condition. To
further extend the life of the SC-1, allow the sensor head to equilibrate to the ambient
temperature before using and do not use it in rain or on leaves covered with dew or water
droplets.
4.2.1 INSTALL BATTERIES
Although the SC-1 has been designed to provide an excellent battery lifespan, the batteries
will eventually require changing. A low-battery indicator will appear in the upper left corner
of the screen.
1. Carefully turn over the SC-1 controller and locate the battery cover.
2. Place the thumb on the grooves and slide the cover off the controller.
3. Remove the old batteries.
4. Insert new ones, orienting them properly.
5. Replace the battery cover.
6. Update the time and date (Section2.1).
4.2.2 CLEAN SENSOR HEAD
Clean the sensor head periodically to remove contamination that can build up during routine
use. It may be helpful to disconnect the sensor head from the controller prior to cleaning.
Items in this section are included with the SC-1; please contact Customer Support to order
missing or replacement parts. The sensor block may become contaminated with dust, sap,
and leaf exudates that can lead to inaccurate readings and drastically increased shake-
down time between readings.
