Features

• Accuracy: ± 0.1% full scale ± 1 decimal place (DC/PT-100/potential meter/resistor/load cell); ± 0.2% full scale ± 1 decimal place (AC).
• It can measure AC/DC voltage, AC/DC current, potentiometers, resistors, transmitters, PT100, load cells, and other signals.
• High-brightness dual-row LED display range: -199999 ~ 999999; display units and decimal points can be arbitrarily configured.
• Communication speeds can reach 38400 bps; sampling times can reach 60 cycles/sec.
• Built-in function to restore factory calibration values.
• It can have functions such as buzzer/input square root/analog output, etc.
• It can automatically reset to zero, maintain (normal or maximum value) / 2-4 alarm levels (high and low alarm levels can be set manually).
• Analog output (15-bit resolution) / RS-485 digital communication interface (the above are optional functions, and both can be present simultaneously).
• High stability, flame-retardant PC casing, high safety.
• CE Standard Certification.

• Note 1: The 2-wire transmitter specification has a built-in 24Vdc excitation power supply, suitable for 2-wire (loop power) transmitters such as pressure, temperature, and humidity transmitters, and can be directly wired for use.
• Note 2: The 3- or 4-wire transmitter specifications provide a 24Vdc excitation power supply, suitable for 3- or 4-wire transmitters such as pressure, temperature, and humidity transmitters, and can be directly wired for use.
• Note 3: Two 5Vdc excitation power supplies for the load cell can be connected in parallel, while a 10Vdc excitation power supply is for single-cell use only.
• Note 4: For alarms with 3 or more relays, only A (NO.) contact output is provided.
• Note 5: The OC alarm provides output from the CE pin of the optocoupler NPN.
