Actions to take in the event of failure and malfunctioning○If a Manostar product (instrument) does not operate normally, by referring to the investigation procedures shown below,
investigate the product yourself to see whether the malfunctioning has been caused by an instrument failure, pressure
detector, or the piping system.
○If an investigation has made clear that the instrument has failed, contact us via the following.

Periodical calibration of instrument○In general, to retain the service life and reliability of an instrument for a long period, it is important to prevent stress due toexternal factors from being applied to the instrument. It is not necessary to conduct maintenance, lubrication in particular, aslong as the instrument is appropriately used in accordance with the instruction manual. However, we recommend that you
conduct periodic calibrations once a year. For periodic calibrations, contact the distributor or us.
○Please be advised that depending on the condition of the instrument, we may decline your request for calibration.

MaintenanceCalibration service○ In our calibration service, we conduct calibration of products and make optimum adjustments in accordance with the condition of eachproduct.
We provide the services of maintaining the accuracy and reliability of instruments by returning them in good condition to customers.
*We provide calibration services for our products only.

FR51A

Types of calibration service• Standard calibration: We conduct calibration and optimum adjustment of the instrument.
• Speedy calibration: We conduct calibration and optimum adjustment of the instrument in a short period. (Speedy calibration
requires an extra fee in addition to the fee for the standard calibration.)

MS99

What is optimum adjustment?
It refers to an adjustment conducted by us to make the instrument indicate values as close to the true values as possible regardlessof whether the calibration result is within or outside the tolerable range.

or outside the guaranteed accuracy range. (For instruments compliant with RoHS only)
However, if a product that is to be adjusted is already in the optimum condition, we will not
conduct optimum adjustment.

When you do not desire optimum
adjustment:

Documents to be issued
When optimum adjustment is conducted: W e will issue inspection reports (two copies) listing data before adjustment and data afteradjustment, respectively.
When optimum adjustment is not conducted: We will issue an inspection report of the calibrated data only.
*We will issue a calibration certificate and a standard calibration certificate, each for a fee. The expense for the inspection report isincluded in the calibration service fee.
OthersWhen a product is be calibrated but cannot be calibrated, we will contact the customer and report whether it can be repaired or not.

Repair service○We will repair products requested to be calibrated that require repair, and products requested to be repaired.
*We provide a repair service for our products only.
*We cannot repair products not compliant with RoHS.
Documents to be issued
When we have conducted a repair, we will issue an inspection report after the repair (one copy).
