Frequently Asked Questions
Q: What analog input signals does this digital display meter support?
A: The CKCTINNER analog input display meter supports voltage inputs of 0–10V and 2–10V, as well as current inputs of 0–20mA and 4–20mA. You can also fine-tune the accepted input range using offset and gain parameter settings, making it compatible with a wide variety of sensors within those ranges.
Q: What is the difference between the NR, 485, and RL versions of this meter?
A: The NR (Standard) version is a straightforward analog input display meter with no additional communication or output features. The 485 version adds an RS485 communication port using the standard Modbus-RTU protocol, enabling the meter to connect to PLCs, SCADA systems, or other meters in a network. The RL (Relay Output) version includes a normally open relay rated at 3A 30VDC / 3A 250VAC, allowing you to trigger alarms or control external devices based on the measured value.
Q: How do I install this panel meter and what size cutout do I need?
A: This digital display meter is designed for standard panel mounting. The mechanical body measures 78×42×25mm, and you will need a panel cutout of 76.5×39.5mm. Simply slide the meter through the cutout and secure it with the included mounting hardware. No special tools are required for installation.
Q: Can this meter display actual physical units instead of just a percentage?
A: Yes. By default, the meter displays readings as a percentage of the input range. However, you can configure a custom display range using the F0-2 through F0-4 parameter settings via the built-in buttons, allowing the meter to show actual engineering units such as degrees, RPM, bar, or any other unit relevant to your sensor.
