9-3. Display of displacement
The displacement is displayed on the header on Multi display.
Please refer to the page 17 for setting.
9-4. Display of displacement at peak force
This function is recommended when graphing is not needed such as destruction test.
When displacement is displayed on the header at Peak mode on Multi display, the
displacement at peak force is displayed.
* The displacement corresponds to the force value on the middle display on Multi display.
* The displacement is not displayed when [1st Peak], [2nd Peak] and [1st / 2nd Peak] is chosen as
SEND button setting. In this case, the displacement can be only saved and sent to external
equipment. (Send Functions: Refer to page 21.)
9-5. Displacement Zero
Zero displacement only.
Press (MENU button) at measurement display and choose displacement on the
header on Multi display. Press (ZERO button) to zero displacement.
* When a peak load value is indicated in middle display, you cannot zero displacement.
In this case, displacement value at peak load value is indicated.
• When you choose [Manual], make sure to check the difference between
the displayed displacement value and the actual displacement, by using
digital length meter and so on.
• The battery is consumed more when connected with a test stand with
linear scale. Please connect AC adapter or charge frequently when long
hours operation.
9-2-2. Connectable displacement scale
Please use displacement scale to meet the followings.
Output specifications of displacement scale
- Line driver output
*Line receiver in accordance with RS-422/485must be built-in.
- Open collector output
*Voltage difference between points of contact must be below 0.5V.
* Some displacement scale may not work.
* There are some displacement scales which we have inspected their working condition with ZTA
and eZT. Please contact us for further information.
Voltage and current from a HTGA torque gauge to a displacement meter
ZTA series and eZT can provide voltage up to DC+5V, and current up to 200mA to
displacement meters. When you would like to supply power from a ZTA and eZT to
external equipment, please Make sure to connect it to an included AC adapter.
* Operation of this instrument could be unstable when over 200mA is provided.
9. Measurement of Displacement (ZTA, eZT only)
It uses phaseA and phaseB together to know the
direction. It reads incremental signals input in the 2
phases. An up/down edge is regarded as 1 count,
in other words, please input a quarter of 1 signal period.
For example
In the case when you combine a ZTA with the displacement scale which uses line
driver output with 20
μ
m signal period.
-> 20
μ
m/4 = 5
μ
m, therefore, “0.005” should be input as a manual coefficient values.
