1. BEFORE YOU BEGIN

Every OVAL product is thoroughly tested and inspected before shipment from our factory. 

When  received,  its  appearance  should  be  inspected  for  possible  damage  by  rough  handling  during 

transit. First of all, thoroughly read the handling precautions described in this section. For topics other 

than those covered in this section, refer to the respective sections of this manual.

If at any time in the future you seek our assistance, contact the nearest sales office in your area.

1.1 Confirming the Nameplate

The  instrument  is  adjusted  to  individual  specifi-

cations  before  shipment  from  our  factory.  Model 

number appears on the nameplate attached to the 

top of the housing. 

Make sure to see that the instrument you received 

conforms  to  the  General  Specifications  (page  16) 

and the Product Code Explanation (page 8).

When  you  inquire,  supply  complete  informa-

tion  as  to  the  product  name,  model  number, 
product  number,  ratings,  and  other  pertinent 
information.

1.2 Transportation Precautions

(1)  In  order  to  safeguard  against  damage  during  transit,  transport  your  instrument  to  the  installation 

location in the original package used for shipment from the factory if possible.

(2) Use care to avoid impact shocks to the instrument during transit.

1.3 Storage Precautions

If the instrument upon receipt is to be stored for extended periods of time before installation, unexpected 

problems could arise. If such is the case, the following considerations should be taken:

(1) The instrument can best be stored in the original package used for transit from the factory.

(2) The place of storage should meet the following requirements:

  Free from rain and water

  Free from vibration and impact shocks

  With minimal temperature and humidity variation (around 25

°

C and 65% R.H.)
