1. To within 2% of set point. Response time specification shown is with "soft start" feature disabled. With soft start enabled, response time will increase by a factor of approximately 4 to 5 times stated specification. Modules are shipped with this feature disabled.
2. Maximum deviation from stated accuracy specification.
3. VCR® connections are available on special order.
4. Dimensions include compression end connectors.
5. 1" or 11⁄2" NPT or 1⁄2", 3⁄4" or 1" compression connections available on special order.
