[6]  MAINTENANCE

1. This section is very important for safety. Read and understand the following 

instructions fully and maintain your instrument properly.

2. To maintain safety and accuracy, calibrate and inspect the instrument at 

least every year.

6-1   Maintenance and Inspection

Before use, check the instrument to confirm that there is no abnormality and that 

the CT can be opened and closed smoothly. If anything is abnormal, do not use the 

instrument and return it to your authorized Sanwa agent or distributor for repair.

6-2   Calibration

For more information, please contact Sanwa’s authorized agent / distribute 

service provider, listed in our website.

 

See section 7-3.

6-3  Cleaning and Storage

1. The panel and case are not resistant to volatile solvent and must not be 

cleaned with thinner or alcohol. If the instrument gets dirty, wipe with a soft 

cloth moistened with a small amount of water.

2. The panel and case are not resistant to heat. Do not place the instrument 

near heat-generating devices (such as a soldering iron).

3. Do not store the instrument anywhere it may be subject to vibrations or could fall.

4. When storing the instrument, avoid hot, cold or humid locations, locations 

exposed to direct sunlight, or locations where condensation is anticipated.

5. When the instrument is not going to be used for an extended time, be sure 

to remove the batteries.

6-4  Battery replacement

• Batteries shipped with the instrument

The batteries loaded at the factory are monitor batteries, so their service life 

may be shorter than that of brand-new batteries. Monitor batteries are a type 

of battery used to check the functions and performance of a product.

1.  To avoid electric shock, do not remove the battery compartment cover while an 

input is applied to the clamp sensor or the instrument is measuring something.

2.  Make sure that the instrument is set to OFF before replacing the batteries.
