WinCT-AD4212C

Ver1.13 Addition to Manual
A&D Company, Limited 16.07.29 Ver1.01

1. Overview
This manual is for users who wish to adjust the response settings of the AD-4212C Electronic Balance
beyond the standard settings.
You can make minor alterations to the response settings of the AD-4212C Series by changing theinternal memory. To make changes to the memory the Windows PC application, WinCT-AD4212C(Ver1.13), and a RS232C connection to the PC are required.
2. Filter Setting
The AD4212C series has two methods of altering settings, Standard Setting and User Setting. Below isa description of each method.
2-1. Standard SettingStandard Setting has three modes: FAST, MID, and SLOW.
Choose FAST to prioritize response time at the expense of lower stability. Choose SLOW for a slower
response time that is much stronger against disturbances.
If the three modes above do not provide the response speed or stability you require, choose User
setting to fine-tune the filter adjustments.
2-2. User Setting
By choosing User Setting you can make detailed changes to the Stability band width, Stability
detect time, Re-zero condition, Averaging range, Averaging time and Digital filter.

A dot ･ in the chart indicates the default setting.
(1) Reading Press the Reading button to display the current internal memory settings.
(2) Storing

After selecting the desired elements press the Storing button to make changes to theinternal memory of the balance.

(3) Zero tracking Zero Tracking
Zero tracking keeps the display at zero by tracking the zero point. When the display is fluctuatingaround zero, strengthening zero tracking will keep the display at zero.
This setting can be selected regardless of filter choice.

setting values for FAST, MID and SLOW for the minimum displays of each model.
User setting allows you to make detailed changes to the Stability band width,

Select User setting to enable these settings.
(5) Stability band width Stability Band Width
A weight is stable if it stays within a specified range (stability band width) for a specified time(stability detection time).
When stable a circle will appear on the display. This circle will disappear when the weight isunstable.
You can use this setting to change the stability band width. Choose smaller values for stricter
judgments and larger values for more open judgments.

Averaging begins when weight variation is within a designated range. When filling very small
amounts, if the averaging range is large, the weight will not deviate from the averaging range and theresponse can be slow. You can reduce the averaging range to increase the response speed. On theother hand, when the averaging range is small, the measured weight can become unstable. In thiscase you can increase the averaging range.

(1) When weight fluctuations are large (exceeding the averaging range set by “Averaging range”), theaveraging process is turned off and the display value follows the fluctuations in weight.
(2) When fluctuations in weight become small, weight averaging is turned on and the weights become
more stable.
(3) The number of values averaged gradually increases and when the preset amount is reached the data
becomes a moving average.

For very small samples or when filling very small amounts, fluctuations in the display can be small (notexceeding averaging range set by “Averaging range”) and the averaging process may not turn off. If theaveraging process does not turn off when a sample is added, the balance will stay in the moving averaging
state, and it will take longer to reach the final value after the sample is placed on the balance.
For this, you should change the “Averaging range” setting and make the averaging range smaller.
However, use caution as a tighter averaging range may reduce the stability.
7. Digit
Digit is the smallest increment displayed by a device (minimum display)Ex 1) When the minimum display of the AD-4212C-301 is 0.0001g, 1 digit = 0.0001g.
With one fewer display digit, the minimum display becomes 0.001g and 1 digit = 0.001g.
With two fewer display digits, the minimum display becomes 0.01g and 1 digit = 0.01g.
Ex 2) The smart range feature of the AD-4212C-301 automatically changes the minimum display when51g or more is loaded on the balance.
For less than 51g the minimum display is 0.0001g = 1 digit
For 51g or more the minimum display is 0.001g = 1 digit
