*1 Do not seal the cable end with taping or adhesive during wiring as it will block atmospheric pressure introduced via the cable. Avoid using a cable with poor ventilation (no clearance within the cable). *2 Max. allowable pressure is the upper limit of pressure value which may safely be applied to the product and remain in specification once pressure is returned to the rated range with a couple of times overpressurization for about 10 minutes. -

6. TRANSPORTATION AND UNPACKING ■6.1 Precautions for Transportation (1) Do not apply vibration as much as possible in transporting the product, as is the case with other electric meters. (2) Never hit or drop the product. ■6.2 Precautions for Unpacking (1) Check the appearance of the carton before unpacking. -
Page 12: Precautions For Possible Water Sprinkling
CAUTION Do not orient glands upward to prevent water from entering via cables. Never pull the cable or bend it extremely. Wiring requires great care so that the self-weight of the cable is not applied to the product. ... - Page 13 CAUTION Atmospheric pressure is introduced into an instrument via the cable. If the cable is pressed due to a clamp, bush, or extreme bend in the middle of the cable, or if the cable is long, the exhaustion of pressure takes time. In this case, an output error may be caused because of pressure within the case or a change in temperature.

Page 18: Operation (Energization)
* When using the same power supply to connect equipment that causes surge or other phenomena, a varistor or the like should be connected to protect the transmitter. CAUTION Before installation, check the rated value specified for this product to determine the rated value of the power supply to use. Internal resistance of equipment to be connected should be within the rated load resistance of the product. -
Page 19: Storage
Induction noise • Keep the product away from the wiring carrying high current. • Keep the product away from electrically charged machines or objects. Conductive noise • Use the stable power supply that is difficult to generate noise. • Install power supply or output measurement equipment in an environment that is impervious to being affected by noise. -
Page 20: Adjustment
Current output can be checked with a check terminal (+CH) without removing any wiring. Use an ammeter with an internal resistance of 10Ω or less during checking. CAUTION Avoid electrostatic charge. To clean the appearance of the product, use a water-soaked soft cloth. - Page 21 12.2.1 Zero adjustment Turn the zero trimmer with a slotted screwdriver to perform zeroing. A positive pressure range and compound range are adjusted differently as shown below. < Positive pressure range > Adjust output in a vented (unpressurized) state to 4 mA DC for the current output product, and to 1V DC or 0V DC for the voltage output product.
