The CT7000 microprocessor-based circular chart recorder measures, displays, records, and controls up to two process variables from a variety of inputs. Record and control functions, alarm settings and other parameters are easily configured via the keys on the front cover and self-prompting displays. The CT7000 offers a 250 mm (10") circular chart and 4-digit LED display(s). Display resolution and filters are user configurable.
Two alarm settings are provided for each pen. Each alarm is user configurable as process high or low, deviation from setpoint (above or below), or deviation band (open or closed within band). An alarm hysteresis adjustment is user configurable. Optional control capability includes on/off and PID control. Output type selections include SPST relay, SSR driver and 4-20 mAdc (user configurable to 0-20 mAdc). Also, 4-20 mAdc outputs may be used for retransmitting the process value. Digital communications is optional.

Can we change the resolution? I tried to change the resolution and made to 2. But when I apply 10bar, its showing 1.00bar. when I apply 1bar then 0.10bar. How can i get 0.01bar resolution in the recorder model CT711000000022
Hi Jack,
Thank you for the inquiry. Set EUU to 1000 , and resolution to 2, if full scale input will be 10.00. Please send request to TEMP@OMEGA.COM if more assistance is needed.
Best regards
OMEGA

Is it possible to retrofit a model to one with analog outputs? I.e. 710200100021 to have analog output ? Or would we need to order new units.
Thank you for your inquiry. A new unit would need to be purchased.
