Product catalog summary
Installation Instructions
The Instromet Humidity Sensor can be mounted on a wall or mast, ensuring it is placed away from heat sources such as heaters, air conditioners, chimneys, and flat roofs. The cable length should remain unchanged to maintain calibration accuracy. Connections are made in a junction box, with specific wiring instructions provided for air temperature and rain sensor terminals.

Specifications
  • Measurement Range: 0 to 98% RH
  • Accuracy at +20°C: ±3% RH (0-90% RH), ±5% RH (90-98% RH)
  • Stability: ±2% RH over 2 years
  • Operating Temperature: -10°C to +60°C

Operating Instructions
The sensor displays outside temperature, which can be shown in Celsius or Fahrenheit. Configuration through the MetAdmin program is necessary for humidity and dew point readings.

Maintenance
The sensor requires no ongoing maintenance due to the absence of moving parts.

Troubleshooting Guide
If the temperature display flashes 'LLL', it indicates a disconnection of the temperature probe. Ensure correct wiring of the blue and white wires. For unresolved issues, contact the service department at 01692 502800.

Humidity-2

Installation Instructions This unit can be wall or mast mounted. It should be fitted where there is free movement of air and away from heater /ventilation outlets, chimneys, warm walls and flat roofs etc. The length of the cable affects the calibration and therefore should not, if possible, be shortened or lengthened. The cable is connected in the junction box with the white two core cable (blue and white cores) connected to the AIR TEMP terminals and the grey (Red Black and White cores) to the rain sensor and RH terminals as per the diagram. If another air temperature probe is being used, such...
