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.

Temperature Measurements
The Product measures the temperature of a type-K
thermocouple (included). Push C to toggle between
degrees Celsius (°C) or degrees Fahrenheit (°F).
W Caution
To prevent damage to the Product or other
equipment, remember that while the Product
is rated for -200.0 °C to +1090.0 °C (-328.0 °F
to 1994 °F), the included type-K
thermocouple is rated to 260 °C. For
temperatures out of that range, use a higher
rated thermocouple.
Display ranges are -200.0 °C to +1090 °C and -328.0 °F
to 1994 °F. Measurements outside these ranges show 0L
in the display. When there is no thermocouple connected,
the display also reads 0PEn.
To measure temperature:
1. Connect a type-K thermocouple to the COM and
terminals of the Product.
2. Turn the rotary switch to M.
3. Push to enter temperature mode.
4. Push C to choose Celsius or Fahrenheit.
