Rated 2 out of 5 by Theman from MORE BUTTONS LABELED The unit needs more controls and they need to be labeled clearly in writing not stupid tiny symbols. Works good but it should not be so difficult to set up.

Questions And Answers

I have a CNi1644-C24 and want to control it from a computer. I can access the communications menus on the controller. The user manual refers me to the Serial Communications Reference Manual, but I cannot find it on your website.

Asked by: C in Pittsburgh

If you click the link under the manuals tab on this page, it downloads a zip file. M3397 is in that zip file.

The menu to have the alarm come on at startup is not showing up. Only the locations for putting in the High and Low temp alarm limits. Have it set at Dev and Band. Everything else working fine except I want the alarm not coming on right away at powerup.

Asked by: Bergie

A.P.oN should always be available. Please try disabling and then re-enabling the alarm sub menu.

Your manual does a good job of explaining how the proportional factor relates to the output level, but not the reset time or rate time. Could you elaborate? Does making those factors larger make it more or less sensitive to I and D portions of error?

Asked by: C in Pittsburgh

Thank you for the inquiry. Please forward this request to temp@omega.com so that we can review PID settings with you. Best regards OMEGA

What is the current resolution (mA) for the DPi32?

Asked by: bochia

The ma resolution would depend on the maximum current being measured. If you were to measure up to 999.9 ma you would have 0.1 resolution and if measuring up to 99.99 ma 0.01 would be your resolution.

I have a CNi-1653-C24. How do I tell which Output options it has? Serial Number is 8150096

Asked by: DKHarris

Hi DKHarris, Model# determines outputs. In this case "53" indicates analog output and a relay output. "C24" indicates RS232 or RS485 output. Best regards OMEGA

I am successfully reading and changing settings on a CNi 1644 over RS232. I am using PID output. I would like to read what the output is. If it is turning on relays 75% of the time, I'd like to read a 75 somewhere.

I have purchased 6 of these meters (CNI*33-EIT) and have them ready to be programmed. Reading all of the service information leaves me a little confused on how to actually program them with my laptop, Do I use a rs485 to rs232 adaptor or rs485

Asked by: catman

Hi Catman, This model has ethernet output only. You can connect to PC via ethernet. Best regards OMEGA

Thanks. I tried your link, but M3397 does not exist on the page, nor does M339. I was at https://www.omega.com/en-us/pdf-manuals. The letters "comm" appear four times, none of which were the right manual. Could you make sure it's available externally?
