How to operate a Concrete Compression Testing machine
Nov 21, 2017

According to the Law of Measuring, the gauge should be inspected annually by the authentic department nominated by local technology inspection bureau.

Except the legal measuring department, clients can not access into the Measuring Standard status to avoid messing up the inner data.

1. Measuring Inspection Operation:

When the gauge is power on, input the serial No. and area No. casually, the gauge comes to measuring status, warm-up for 5 minutes, inspecting by third grade standard loading gauge, the steps are as below:

A. Press 【PEAK VALUE】 key to turn off the 【PEAK VALUE】indicating light.

B.  Loading to rating value (For example, 200T Compression Machine is 2000KN) three time and then unload. Turn off inlet valve, turn on outlet valve loading to inspection point and record the force value displayed in the gauge. When the force come to Max. capacity, turn off outlet valve turn on inlet valve to unload; Repeating three time to calculate accuracy of the force value.

2. Measuring Standard Operation:

      Before ex-work or after using, the compression machine needs to be calibrated the Measuring Standard, the steps are as below:Multi-point calibration CAL1: When the gauge is power on, input the serial No. & area No. casually, the gauge comes to measuring status, warm-up for 5 minutes, loading to rating value (For example, 200T Compression Machine is 2000KN) three time and then unload, doing the Measuring Standard by third grade standard loading gauge, the steps are as below:

Step

Operation

Gauge Displaying

1

Press 【MEASURING STANDARD】 key

2

Press moving key or number key to input password


3

Press “enter”

“CAL1”

4

Press “enter”

“CP---0”

5

Press “enter”

Real-time displaying specimen strength

6

Turn off inlet valve and turn on outlet valve to rise piston for 10mm slowly, press “enter”   before it press the specimen, that is gauge finish “clear” operation.

Real-time displaying specimen strength

7

Press “enter”

“CP---1”

8

Press “enter” directly, or press moving key and number key to revise   strength value, then press “enter”.

Showing the strength value of this Measuring Standard Point, for   instance, “P0200”

9

Turn on outlet valve to load, when the strength value showing in   loading ring approach the strength value of this Measuring Standard Point,   turn off the valve little to load gently, press “enter” simultaneously when   the strength value showing in loading ring reaches the strength value of this   Measuring Standard Point.

Real-time showing relative specimen strength after “clear”

10

Press “enter”

Finish Measuring Standard of first point, showing “CP---2”

11

Repeat step No.8 and No.9, until finish the Measuring Standard of the   last point. Of cause you can escape whenever you press 【CANCEL】 key

Gauge return to measuring status, real-time showing current  strength value.
