General Specification Model CS077-2 Power supply AC100V ∼ 240V 50／60 Hz Measurement -1999mV ∼ +1999mV Resolution 1 mV Accuracy at 25°C ±﹝0.1%+ 2 digits﹞ after calibrating Impedance ohms Set Range -500mV ∼ +500mV Calibration Knob None external Relay Contact 5A for 240VAC Control Output Voltage Same as plug in AC voltage Display 0.56" LED, digits Operating Temperature 0°C ∼ 50°C ﹝32°F ∼ 122°F﹞ Operating Humidity Max. 90% Power Consumption Approx. 2 watts Dimension 150 x 85 x 40 mm ﹝5.9 x 3.4 x 1.6 inch﹞ Standard Accessories Instruction Manual, Adjustment Sticker, Instrument Holder each one.     ORP electrode input BNC terminal can only connect with ORP electrode, it is not allowed to connect with any other electrode. Front Panel Description 1.Display. 2.Set adjustment knob. 3.ORP／SET function switch. 4.Indicator of output in action. 5.Electrode BNC input terminal. 6.Control output socket ﹝Normal Open﹞. 7.Power plug. Operation 1.   Connecting AC power supply. ﹝Make sure the correct voltage.﹞ 2.   Connecting the ORP electrode into the ORP input terminal socket. 3.   Turn the ORP/SET switch to "ORP" position. 4.   Take away the ORP electrode from storage bottle, and clean the electrode with distilled water, then place the electrode into the water. REMARK：   The controller is already calibrated ﹝base on 25°C environment﹞. It needs not to make calibration any more. Please contact with your dealer where you buy when the calibration is necessary to apply. Instruction For Cleaning & Maintenance 1.   The immersed level for electrode should not be higher than the electrode cap. ﹝When use the refillable electrode, the level should be lower than filling open to avoid the water entering into the open and cause damage.﹞ It had better cleaning the ORP electrode sensor with soft brush every 2 ∼ 3 weeks to keep the test accuracy. Please keep the electrode in the storage bottle with 3M KCL buffer solution; the crystallization is normal for the keeping. 2.   ORP electrode is accurate glass product, please do not knock it, and do not use finger, cloth and alcohol to clean it to avoid the damage. 3.   There is protection "dead band" for delaying output control in "turn on" and "turn off" to avoid frequent switching. 4.   Indoor uses only. Why Shouls We Know ORP ﹝Oxidation Reduction Potential﹞ Range To realize it by easy understanding aquarium concepts, The high or low value of ORP shows higher or lower capacity which can oxidize toxic ammonia and nitrite in water ﹝but also oxidize the other materials in water﹞! In short, more pollutants in fish tank, ORP value is relative lower; and is often higher for less pollutant situation. ●A well keeping coral reef aquarium   The reference reading of ORP could be between 360 ﹝just lighted up﹞   and 450mV ﹝duration of switching light off﹞. ●A well keeping freshwater plant aquarium   The reference reading of ORP could be between 250 ﹝morning or just   turn the light up﹞ and 400mV or even higher ﹝evening or just turn the light   off ﹞, ﹝normally the higher ORP reading shows for lower fish population,   and the lower reading shows for higher population.﹞ ●The denitrifying reaction chamber or filter.   The reference reading of ORP should be between -190 and 50mV. ﹝to   avoid produce the poisonous hydrogen sulfide in over reduction, the ORP   value should not be below -190mV﹞. The Common Situation In Higher Polluted Aquarium The common situation is lower ORP value in higher polluted aquarium and the value is not easy to be shifted up. The common ways to take to shift the ORP value up: Use ozone generator, protein skimmer, effective trickle filter or oxygen tower to increase the dissolved oxygen in water, add additives to increase the oxidation potentials CS077-2 DIRECTIONS Download CS077 Series DM Download
