The

SGSM Chart

shows a graph for an SGSM test while the test is running.

“Elapsed Time” - Time since the test began (HR:MIN:SEC)

“State Time” - Elapsed time of the current state.

“SGSM State” - The current state of the SGSM test.

Mixing - The bob is conditioning the cement. The speed is set by the

“Conditioning Speed” field in the Setup screen.

Wait - After conditioning the cement, the motor stops for 6 seconds to

allow the fluid to reach a steady state.

Pre Zero - Before performing the zero operation, the software rotates

the bob one full revolution to overcome any initial drag.

Zero - Before starting the gel strength measurement, the software

rotates the bob one full revolution and records the amount of drag in

the system. It uses these values to compensate for the drag during a

test.

Stop - The bob is stopped between measurements. The amount of

time the bob will be stopped is specified in the “SGSM Wait Time” field

on the Setup screen.

Measure - The bob is rotating and measuring gel strength. The

measurement will last for the amount of time specified in “SGSM Test

Time” on the Setup screen.
