Usage Notes
Reducing the impact of offset drift*
• Wait at least 30 minutes after turning on the device
before making measurements. Offset drift may increase
immediately after power is supplied to the probe due to
self-heating and other factors.
• Offset drift will occur when the ambient temperature
changes or when the device is used to make continuous
measurements over an extended period of time, causing
measured values to include an error component. Perform
demagnetization and zero-adjustment as necessary.
*A phenomenon whereby the magnitude of the zero point error
component (offset voltage) varies over time.
