1. INTRODUCTION Thank you for purchasing the AD-4530 Digital Indicator. This manual describes how the AD-4530 works and how to get the most out of it in terms of performance. Please read this manual completely before using the AD-4530. 1.1. Features The AD-4530 has the following features.
When connecting long cables to the sensors, keep the cables away from power cables and other sources of electrical noise. Do not connect the AD-4530 to the power supply before installation is completed. The AD-4530 has no switch to disconnect the power supply.
To avoid electrical shock, do not touch the internal part of the instrument 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 circuit may occur or measurement errors may occur due to noise.

Select a hold mode in the function mode (f003). 6.2.4. Latch function The AD-4530 can latch the value or output, set by the function (f004), by the ON/OFF timing of the external LATCH input. The latch operation occurs after processing of the hold operation.
The decimal point (Cf01), minimum scale value (Cf02) and rated capacity (Cf03) are set using the function mode. The zero point input voltage (Cf04), the span input voltage (Cf05) and the display value for the span input voltage (Cf06) are set using the calibration mode.
Perform span calibration, and proceed to the storing mode. Cancel span calibration, and proceed to the storing mode. * After span calibration, the AD-4530 displays the mV/V value of span calibration for 3 seconds, and then proceeds to the storing mode.

11. LATCH The AD-4530 can latch the value and output that are set by the function (f004) in response to the external latch input. With regard to the output, first the hold operation is processed, then the latch operation. Sensor input Output value During the latching operation.
Upper limit and lower limit values can be negative. For example, if the upper limit value is -1000 and the lower limit value is -2000, HI is output for the measured value of -500 and LO is output for the measured value of -2500.
OK output LO output 12.4. Hysteresis A hysteresis width and time is provided for the output relay on/off timing to prevent the output terminals from chattering. When the measured value exceeds the set value, the relay is turned on. If the measured value falls below the set value and it is further reduced by the hysteresis width, or if the hysteresis time has elapsed, the relay is turned off.
12.4.1. Hysteresis upward 2-level judgment (f105=1) Relation between HI and OK When the measured value exceeds the set upper limit value, HI is output immediately. Even if the measured value falls below the upper limit value, OK is not output immediately. OK will be output when the measured value falls below the hysteresis width, or when the hysteresis time has been exceeded.
12.4.2. Hysteresis upper/lower limit judgment (f105=2) Relation between HI and OK When the measured value exceeds the set upper limit value, HI is output immediately. Even if the measured value falls below the upper limit value, OK is not output immediately. OK will be output when the measured value falls below the hysteresis width, or when the hysteresis time has been exceeded.
12.4.3. Hysteresis downward 2-level judgment (f105=3) Relation between HI and OK When the measured value falls below the set upper limit value, OK is output immediately. Even if the measured value exceeds the upper limit value, HI is not output immediately.
