If there is any noticeable damage, notify your Dealer. Note: Save all packing materials until you are sure that the instrument functions correctly. All defective items must be returned in the original packing materials together with the supplied accessories. GENERAL DESCRIPTION HI 8510, HI 8512, HI 8710, HI 8711, HI 8720, HI 931500, HI 931501 and HI 932500 are pHORP panel-mounted indicators and controllers designed for simplicity of use in a wide range of industrial process applications. The models are designed with DIN standard panel mount with membrane keypads on the front panel, a large LCD display and autodiagnostic functions (not HI 931500, HI 931501 and HI 932500). Connections to the power supply, contacts and recorders are made through screw terminals on the rear panel. Two models are available for HI 8510, HI 8711, HI 8512, HI 8520. The E-model accepts input direct from the pH or ORP electrode, while the T-model accepts a 2-wire current loop of 4 to 20 mA from a pH or ORP transmitter. HI 931500, HI 931501 and HI 932500 are equipped with a BNC socket to connect a pH-ORP electrode. Other features include: recorder output in 0 to 20 mA or 4 to 20 mA; LED indicators which identify the controller mode. 3 Using the pH indicators in conjunction with a 4-20mA output pH transmitter HI 8614 or HI 8614L (with LCD display) and using the ORP indicators in conjunction with a 4-20 mA output ORP transmitter HI 8615 or HI 8615L (with LCD display) will assure you of a strong, interference-free signal at distances up to 300 m (1000 ft). All instruments are supplied with a plastic transparent front cover and mounting brackets (electrode and mains cable excluded). 4 MECHANICAL DIMENSIONS The meters have a DIN 43 700 casing in black anodized aluminum. Front and back of the instruments are supplied with shockproof ABS plastic and a transparent protective cover for the front panel.
