7. Maintenance
Do not unscrew and remove the housing!
7.1. Cleaning
NOTE: Any liquid residue should be wiped off immediately.
Except for wiping the surface with a wet cloth and replacing the battery from
•
time to time when exhausted, the meter requires no maintenance.
Use a soft cloth or lint free paper tissue to clean the sample vial compartment
•
periodically. Remove debris, scale, and deposit promptly.
Although The AP50MM is protected from water damage, it is a good practice to
•
avoid water entering the sample vial compartment and becoming trapping
underneath the navigational control pad. Deposits left behind when the water is
evaporated could affect Ohaus performance.
- Attention: Do not use solvents, harsh chemicals,
ammonia or abrasive cleaning agents.
- The housing may be cleaned with a cloth
dampened with a mild detergent if necessary.
7.2. Storage
The AP50MM should be stored in the temperature range of 0 to 140°F (-18 to 60°C)
and relative humidity less than 85% at 106 °F (41 °C). Do not leave the AP50MM in a
parked vehicle. The temperature inside a parked vehicle can reach above 150 °F in
summer and -20 °F in winter. Exposing the AP50MM to extreme temperature or
humidity will cause a gradual decay in performance of colorimetric measurements
and require more frequent calibrations.
•
During storage and transportation, do not leave a sample vial in the sample
vial compartment. Close the lid of the sample vial compartment during
storage and transportation.
Replace batteries when the AP50MM displays a warning message
•
indicating LOW BATTERY voltage. Remove batteries from the AP50MM
battery compartment if the AP50MM is going to be placed in storage for a
long period time.
When the AP50MM is shipped, a desiccant pack is included in the desiccant
•
compartment underneath the cover of the battery compartment. It is
recommended that a new desiccant pack is replaced each time the batteries
are replaced.
