3½D LCD Digital Panel Meter Model : LC035 User Manual 1. FEATURES : 200mV full scale input sensitivity. Single 9V DC operation. Decimal point selectable. 13mm figure height. Automatic Polarity indication. Guaranteed zero reading for 0 volt input. High input impedance ( 100 MV ) Easy Bezel fixing Method. 2. APPLICATIONS : a) Voltmeter f) Current Meter b) Thermometer c) PH Meter g) Capacitance Meter h) Lux Meter d) DB Meter i) LCR Meter e) Watt Meter j) Other industrial & domestic uses. 3. SPECIFICATIONS : Maximum Input Maximum Display Indication Method Measuring Method Overrange indication Reading rate time Input Impedance Accuracy Power Dissipation Decimal Points Supply Voltage Size : 199.9mV DC : 1999 counts (3½ Digit) with automatic polarity indication : LCD Display : Dual-Slope Integration A-D converter system : 1 shown in the display. : 2-3 reading per second. : 100MV : ± 0.5% of full scale (23 0 ±5 0 C 80%RH) : 1mA DC : Selectable with wire jumper : 7-11V DC : 68mm x 44mm 4. OPERATION : a) If needed, add proper voltage dividers (not included) and decimal point wire jumper. Max. Voltage Proper Voltage Decimal Point to be measured Divider fixing method 200mV - Shortcircuit P1 on & P2, P3 off 20V Disconnect wire Shortcircuit P2 on jumper in RB & P1, P3 off RA = 100KV, RB = 9.9MV 200V Disconnect wire Shortcircuit P2 on jumper in RB & P1, P3 off RA = 10KV, RB = 9.99MV 500V Disconnect wire jumper in RB RA = 1KV, RB = 9.999MV Shortcircuit N on to enable polarity sign function or shortcircuit N off to disable polarity sign function RA and RB are ½ W 0.5% Metal film resistors. b) Connect 7-11 DC power supply to panel meter. Pay attention to the proper polarity. c) For range other than 200mV, input accurately ½ x Max. Voltage generated by calibrator ( e. g V for 200.0V range) and carefully adjust the semifixed resistor R4 to have some reading in L.C.D. d) Connect the input voltage to be measured to V in and GND. The input voltage should be DC only. 5 6 NOTE 7 8 3½D LED Digital Panel Meter Model : LC135 User Manual 1. FEATURES : 200mV full scale input sensitivity. Single 5V DC operation. Decimal point selectable. 14.2mm figure height. Automatic Polarity indication. Guaranteed zero reading for 0 volt input. High input impedance ( 100 MV ) Easy Bezel fixing Method. 2.

OPERATION : a) If needed, add proper voltage dividers (not included) Max. Voltage to be measured Proper Voltage Divider 200mV - 2V 20V 200V 500V RA = 1.1MV, RA = 9.9MV RA = 100KV, RB = 9.99MV RA = 10KV, RB = 9.99MV RA = 1KV, RB = 9.999MV RA and RB are ½W 0.5% Metal Film Resistors. b) Connect 5DC power supply to panel meter. Pay attention to the proper polarity. c) For range other than 200mV, input accurately ½ x Max. Voltage to be measured, ( e. g V for 200.0V range) and carefully adjust the semi-fixed resistor pot R2 to have some reading in LED display. d) Connect the input voltage to be measured to V in (+) and V in (-). The input voltage should be DC only. Shorting S will display the corresponding decimal point S Note : Please ensure that when shunt is use, it must be connected on the ground / common side of the load and not on the supply side. 5 6 NOTE 7 8 Terminal Pin Connection for GM035 3½ Professional LED Module Model : GM035 LO BAT DP3 DP2 DP1 TERMINAL 1 15 Terminal Output Description 1 BP Blackplane output Terminal Input Description 2 V+ Positive power supply 9V - 5mA 3 V- Negative power supply 4 DP3 5 DP2 6 DP N.C.
