Maintenance and Safety Considerations

Calibrating the Meter

Any instrument with analog circuitry (including preamplifiers, filters, etc.) may change in performance over
time. Regular calibration will keep your instrument in optimal working condition to support your test, design,
troubleshooting, and manufacturing needs.
It is recommended to calibrate and verify the instrument at least once per year to ensure that it meets the
stated performance specifications.
To avoid damaging the default calibration data stored in device memory, instrument calibration should
only be performed with appropriate equipment by qualified personnel at a Deviser Instruments, Factory-
Authorized Service Center.
Environmental conditions:
Calibration and verification tests should be performed in a laboratory where the ambient temperature and
relative humidity can be controlled.
Warm up:
Allow up to at least 5 minutes' warm- up before calibrating the instrument. If the unit has been exposed to
or stored in a high-humidity (condensing) environment, allow more time.
For detailed information on calibration procedures, please contact an authorized Deviser distributor.

Other Safety and Maintenance Tips

Please charge and discharge the battery every 3 months to extend battery life. Recharge the battery only
in the instrument; If left unused, a fully charged battery will discharge itself over time.
Never use a damaged or worn-out adapter or battery. During charge, the unit may be warm to the touch
even if it is powered off. To avoid overheating, always disconnect the unit from the AC adapter before
storing it in the carrying case.
CAUTION: Extreme temperatures will affect the ability of the battery to charge. Allow the battery to return
to room temperature before use or charging. Storing a battery in extreme hot or cold temperatures will
reduce its capacity and lifetime. It is recommended to store batteries at temperatures less than 25°C.
The unit cannot be used in its carrying case for more than 1 hour if the ambient temperature exceeds 35°C.
CAUTION: Use only the original AC-DC adapter and battery to power the unit. To charge, simply insert the
battery into the unit's back panel, plug in the AC-DC adapter, and switch the power on if necessary. If the
LED is red, the battery is charging. When fully charged, the LED will turn green. Time required to fully charge
a depleted battery is approximately four hours, but may be longer if the instrument is in use while charging.
CAUTION: While updating firmware, the unit must remain connected to power and at more than 60%
battery power. If power fails during the updating process, instrument function may be affected.
DANGER: The S7200 contains an optional VFL (Visual Fault Locator). To avoid eye damage, never look
directly into the VFL output port while the light is on, and wear appropriate eye protection when necessary.
