5.1 Kaperawatan Probe

The measuring probes are made of SUS316 stainless steel for durability and a long service life (up to 5,000 vertical plug and pull cycles). To ensure continued accuracy and longevity:

• Always replace the probe protection sleeve when the meter is not in use.
• Avoid bending or damaging the probes.
• Clean the probes with a dry cloth after each use to remove any residue.
