XW Warning To prevent electric shock or personal injury, do not use the low-pass filter when you measure for hazardous voltages. Voltages larger than what is shown can be present. First, make a voltage measurement without the filter to see if a hazardous voltage is present. Then, select the filter. Note When the low-pass filter is selected, the Product goes to manual range mode. Push  to set the range. The Product does not autorange with the low-pass filter set. 1 kHz 100 Hz Figure 3.

Warning
To prevent electric shock or personal injury,
do not use the low-pass filter when you
measure for hazardous voltages. Voltages
larger than what is shown can be present.
First, make a voltage measurement without
the filter to see if a hazardous voltage is
present. Then, select the filter.
Note
When the low-pass filter is selected, the Product
goes to manual range mode. Push
