Q. In these days of increased awareness of the environment, why does Instron still use “standby” modes on your systems?
A. Strain gauge load cells convert the load acting on them into electrical signals. The gauges themselves are bonded onto a structural member that flexes when weight is applied. Temperature effects on the modulus of elasticity of the flexure materials are compensated, using carefully trimmed temperature-sensitive resistors. But it is still necessary when starting a system from a full shutdown state to allow a 15 - 20 minute “warm-up” period that allows the load cell temperature to stabilize and ensures consistent measurements. Standby mode is provided to permit the automatic shutdown of the energy-consuming components of a testing system after a period of inactivity, but it retains the power supply to the load cell to ensure that it remains temperature stable.
