5.2 FITTING THE BATTERIES

The Elcometer 138 Conductivity Meter uses dry cell batteries only.
Two CR2032 lithium batteries are supplied in the kit.
To fit or replace the batteries:
1 Place batteries in battery clips ensuring
correct polarity.
2 To reassemble the meter, slide the sensor
onto the body of the meter and push the
body and sensor together gently until
sensor retaining clip engages.
When the battery voltage becomes low, the low
battery warning indicator will flash. Replace
both batteries immediately.
Note: Lithium batteries must be disposed of carefully to
avoid environmental contamination. Please consult
your local Environmental Authority for information on
disposal in your region. Do not dispose of any
batteries in fire.
