Questions answered in these manuals
How do I adjust the zero offset after installation?
Use the zero‑adjustment potentiometer on the front left side of the instrument with a flat‑head or Phillips screwdriver to reduce any zero‑offset up to about +1 % when mounted horizontally.
What is the correct wiring for the 4‑20 mA current output?
Connect the left‑side negative (‑) terminal and the right‑side positive (+) terminal; link the power positive to the PDT101 positive terminal, the power negative to the BCS 4‑20 mA input negative, and the PDT101 negative terminal to the BCS input positive.
What type of cable should be used for the transmitter connections?
Use shielded cable, but do not connect the shield to the transmitter side.
How can I download the English version of the PDT101 manual?
You can download the English version from the Vaisala website at www.vaisala.com/PDT101.
How do I adjust the zero point of the PDT101?
Turn the zero‑point adjustment potentiometer on the front of the unit with a 2.5 mm (0.098 in) screwdriver to minimize zero‑point offset.
How should the PDT101 be mounted?
It can be mounted on a wall using M4 or M5 screws through the provided mounting holes, or on a DIN rail EN50022 using the supplied clips.
