This chapter contains information about how to change the parameters and settings for
your measurements and all the details about each feature and function.
3.1 Measurement Configuration
The following information will guide you through ways to configure measurement
functions. It provides you the flexibility to change any parameter in any measurement
function when needed, including ADC setting, filter, resolution setting (digits), DC input
resistance, threshold resistance (continuity), range (manual & auto), rate (integration
time), sensor type for temperature measurements, remote interface selection and input
terminal switch.
3.1.1 Set ADC (Auto Zero)
Zero
The purpose of Auto Zero functions are used for minimizing the offset influence on your
measurements. When Auto Zero is enabled (no individual setup), DL-2060 takes the
input signal reading as a base value and then internally disconnects the input signal, and
takes a offset reading (a null offset). It then subtracts the offset from the base to get an
accurate measurement.
Displayed reading = Base value (input signal)
– Offset value
When the Auto Zero is enabled the meter takes an offset reading for each subsequent
measurement. However, when Auto Zero is disabled, the meter only takes one offset
reading each time when you change the function settings.
Defaults
The default settings for Auto Zero are enabled . The user selected values for Auto Zero
are stored in a volatile memory and the default settings will be restored when the meter
is power-off.
