Through Status Input Signal; Through Link Top Communication - Oval ALTI mass CA00A Instructions Manual

9.8.2 Through status input signal

You can perform the zeroing with status input signal. Follow the procedure given below for preparation
and operation:
(1) Preparation to assign status input to zeroing
・Set status input function to "Auto Zero".
(For details of setup, see 9.15 Status Input and 9.2.5 Transition chart (4) [No. 2-5-1].
・Set input mode of status input.
(For details of setup, see 9.15 Status Input and 9.2.5 Transition chart (4) [No. 2-5-2].
(2) Preparation to assign zeroing in progress to status output
(You can perform the zeroing without this setting. You may omit this procedure if not required.)
By completing the settings that follow, you can monitor the zeroing status with status output.
・Set function assignment of status output to "Error Status".
・Set adjustment item of status output to "On".
・Set working output of status output. (For detail of setup procedure, see 9.14.3 Status output and
9.2.5 Transition chart (4) [No. 2-4-5-1], [No. 2-4-5-2-8], and [No. 2-4-5-3].
(3) Procedure to run the zeroing
By working with separately input, you can perform the zeroing. Follow the procedure outline below:
① Preparation
Verify the following precautions:
During the zeroing, fill the sensor unit completely with the fluid the temperature of which is
within ±10℃ from the temperature at which it operates.
CAUTION: 1. Fluid (liquid or gas) must completely fill the sensor unit and be absolutely
at zero flow.
2. Accurate zeroing cannot be achieved unless fluid flow is completely halted.
3. Ensure that the shutoff valves, etc. have no leaks.
② Run the zeroing: set the status input to 0.3 sec or longer in the "Short" (when input mode is
"Short"). Upon detection of an input, the zeroing process starts and this process lasts in about
30 seconds.
In the event zeroing has failed, you cannot expect accurate measurement. Upon completion of
zeroing, do not forget to run a check for possible errors.

9.8.3 Through Link Top communication

Zeroing can be conducted through communication, using the software Link Top. For detail of procedure,
see the Link Top instruction manual.
NOTE: This function is disabled in Write Protect
mode (refer to section 9.2).
