Unpack the digitalindicator carefully and confirm that all items are present.1.1. Precautions Before UseAvoid water and moisture.Avoid vibration, shock, extremely high temperature and humidity,direct sunlight, dust, and air containing salt or sulfurous gases.Avoid places where inflammable gases or vapors are present.The operating temperature is -10°C to +40°C.A 100 VAC to 240 VAC power source is required. Use a stablepower supply free from sudden dropout or noise as they can causemalfunctions. Avoid sharing the power line.Keep cables away from power cables and other sources ofelectrical noise.Connect only a non-inductive load of 10 kΩ or more to the analogvoltage output terminals.Connect only a non-inductive load of 510 Ω or less to the analogcurrent output terminals.When connecting long cables to the sensors, keep the cablesaway from power cables and other sources of electrical noiseDo not connect the AD-4530 to the power supply before installationis completed. The AD-4530 has no switch to disconnect the powersupply.Use shielded load cell cables.Do not connect too many sensors. Otherwise, instrument damage mayoccur.1.2. Precautions During UseThe AD-4530 is a precision instrument that measures the microvoltoutput from sensors. Prevent noise sources such as power lines,radios, electric welders or motors from affecting the instrument.Do not try to modify the AD-4530.In all hold modes, the hold data is saved digitally, so there is nodrooping of the value displayed on the display panel or the analogoutput. Note that the hold function is disabled when the AD-4530 isdisconnected from the power supply.Disconnect from the power supply before removing the cover.When removing the cover, make sure that the power is off.Do not touch the instrument immediately after it is disconnectedfrom the power supply.To avoid electrical shock, do not touch the internal part of theinstrument within ten seconds after switching the power off.Be sure to fasten all the screws completely.Loose screws may come off during operation and a short circuitmay occur or measurement errors may occur due to noise.2.

OPTIONS4.1. OptionsAD-4530-200: Relay outputAD-4530-030: RS-485AD-4530-040: RS-232CAD-4530-007: Analog outputAD-4530-237: Relay output, RS-485, analog outputAD-4530-247: Relay output, RS-232C, analog outputNote: Only one option can be installed in the AD-4530 at a time.4.2. Installing an option1. Remove the two screws that secure the guide rail, and then removethe guide rail.2. Remove the two screws that secure the case.3. Pull the case out from the front panel (holding it as shown).4. Remove unnecessary blank panels with nippers, etc.5. Insert the option board at the position specified on the rear of the frontpanel.6. Reattach the case and guide rail by reversing the steps above.5. FRONT PANEL5.1. DisplayDisplays a measured or set value. To set the decimal point position, usefunction mode Cf01. The display is composed of four seven-segmentindicators plus a minus sign.5.2. Status indicatorsName Description1 HI Turns on when the measured value is greater thanthe upper limit (HI).2 OKTurns on when the measured value is equal to or greaterthan the lower limit and equal to or less than the upperlimit.3 LO Turns on when the measured value is less than thelower limit (LO).4 DZ Turns on when adjusting the digital zero.5 HOLD Turns on when a value is being held.5.3. KeysOperation FunctionPress to proceed to the upper limit valuesetting mode.When inputting a numerical value, press tochange the polarity.Press to proceed to the lower limit valuesetting mode.When inputting a numerical value, press tocancel the setting.Press to turn the digital zero on.When inputting a numerical value, press toshift the position of the blinking digit to theright or change the function group.+ Press to turn the digital zero off.Press to turn holding on or off.When inputting a numerical value, press tochange the blinking digit or change thefunction parameter.Press to output the serial data (print).When inputting a numerical value, press toenter the setting.+Press to proceed to calibration mode.+Press to proceed to function selectionmode.+ +Press to proceed to selection mode in thecheck mode.* The digital zero function sets a desired measurement point as zero anddisplays the deviation from this zero point. When measuring a load, it canbe used as the tare, etc.* The zero value is saved in non-volatile memory (EEPROM). This zerovalue is retained even after the power has been turned off and on (orpower is lost).* To change the digital zero operation, use the function Cf11 .To protect against accidental operation, press and toturn the digital zero on or off.5.4. Operation mode- Upper / lower limit setting modeUse this mode to set the upper and lower limit of the comparator.- Calibration modeUse this mode to perform zero and span calibration with an actual load.- Function setting modeUse this mode for setting functions.- Check modeUse this mode to confirm input and output operation.6.
