To configure analog output with Insight:
1. Check that the output parameter selection DIP switches on the transmitter component
board are switched to the OFF position.
2. Connect to Insight and select > Configure Device > Analog Output 1[2].
3. Select the output mode (either 0 … 10 V, 0 … 5 V, 1 … 5 V, or O).
4. Select the output parameter.
The default analog output setup for HMD65 is 1 channel for RH and 1 channel
for T. Using Insight, you can set any RH and T output combination for the 2
channels (RH+RH, T+T, or RH+T).
5. Enter the lower and upper limits of the output scale for your selected parameter.
6. Set the error output value and the output clipping and error limits.
7. Select Save to store the configuration and exit the menu with Close when done.
4.4.1 Testing and Adjusting Analog Output Voltage (V) Level
• Computer with Windows operating system and Vaisala Insight software
installed
• Vaisala USB cable 219690 for connecting the probe to Insight
• Multimeter for checking the analog output voltage reading
Note that configuring these settings requires using Insight in Advanced Mode.
You can test the voltage (V) output level of the transmitter with a multimeter, and adjust the
output level (2-point adjustment) if necessary.
