:AZERo[:STATe] <b>
:SYSTem:AZERo[:STATe] <b> Control Autozero
Parameters
<b>= 0 or OFF
1 or ON
Description
With autozero disabled, measurement speed is increased. However, the zero and gain
reference points will eventually drift resulting in inaccurate readings of the input signal. It is
recommended that autozero only be disabled for short periods of time.
NOTE See "Performance
:LSYNc <b>
:SYSTem:LSYNc <b>
Parameters
<b>= 0 or OFF
1 or ON
Description
When enabled, A/D conversions are synchronized with the power line frequency. This
reduces noise at the expense of speed. Line cycle synchronization (LSYNC) is not available for
integration rates <1 PLC, regardless of the LSYNC setting.
NOTE See "Performance

:SYSTem:LFRequency?
Description
On power-up, the Model 2182 detects the line power frequency and automatically selects the
proper line frequency setting. The line frequency setting can be checked using this command.
The response message will be 50 or 60. The value 50 indicates that the line frequency is set
for 50Hz (or 400Hz), while 60 indicates that it is set for 60Hz.
