<< Applications The Instrument can measure any range of Current or Voltage signal input. The user can select data remained or top value remained. The instrument can be use with 2 wire transmitter, Pressure Sensor, 4 wire weight Sensor and so on. For Nonlinear input, the instrument can process for 20 stages. As well the instrument can be with RS485 communication. The input, output and the power supply is isolated. Name of Parts 2. When used with Pressure sensor. The Instrument can supply DC2V auxiliary power & the sensor output is 2mV/V. Select input signal mv. 2 90~260V AC 6 3. When used with Ohm meter. Input 0-400Ù Select input signal rt. 8 24V+ 8 Gnd +mv 20 PV SV <</RST V(mV) AL Ù(ºC) AL2 V (ma)al3 << Malfunction Estimate:. No Display : Check all the connection & wiring if it is correct. Specially pay attention to the power supply terminals & signal input terminals, please do not wrong connect. As well pay attention to do not short the output terminals by strong current. 2. Wrong Display : Check it the PVF=0.00 Check if the input signal is conformity with the selected symbol. For RTD input, please use low impedance cable. The 3 wire should at the same length. 3. Wrong Control : When the instrument lost control, please check if the output diagram connection is correct. Or check if the components for output part damaged. 4. UUUU, LLLL : When the instrument displays "UUUU", it means the input signal exceeds the measured Usp range. When the instrument displays "LLLL", it means the input signal lower the measured Lsp range, or input signal terminal connection is Measured Value (PV) / Various Parameter Symbols Parameter Value / Rate Value / ct / AL Indication Lamps for Alarm V(mV) AL ON : Output OFF : No Alarm Indication Lamps for Alarm 2 Ù (ºC) AL2 ON : Output OFF : No Alarm Output Unit Indication Lamp / Alarm 3 (ma) Select / Confirm Key Shift / Clear / Reset Key Up Key Down Key 2 Page - 02/ V 9 20 R 90~260V AC 2 Page - /

Rate Setting : In displaying estate, press <</RST key and LED flashes, then you can modify the value by Up and Down key. The factory setting is.00. Once the user want to set it to be other value, then PV=Rate (USP-LSP) + LSP USP means Up limit, LSP means Down limit. << Decimal Point Setting : 0~3 Stands for 0000, 000.0, 00.00 and 0.000 AL Hysteresis Range : ± 50.0 AL2 Hysteresis Range : ± 50.0 AL3 Hysteresis Range : ± 50.0 3. Zero Point Clear : In the displaying estate, without key operation, when the input zero point, press and hold <</RST key for more than 2 seconds. It is for the sensor zero point clear. 4. The instrument will return to the measuring estate without any operation for 25 seconds. Special Function : The instrument can be input by up to 2 signals, the up and down LED can display the measuring value. The instrument can calculate the two input value, so it also can be used as a watt meter. 8 Page -08/ 5 Page - 05/
