Resistance and Continuity Measurements
WARNING
: To avoid electric shock or damage to the meter, remove power to the circuit under test and discharge
all capacitors.
1) Set the Function switch to the
position.
2) Insert the test leads to the meter as follows: Red lead to “V,Hz,
” terminal; Black lead to the
COM input.
3) With the pointed end of the test leads measure resistance. Remember that resistance
measurements are made in parallel with the device or circuit under test.
4) Read the resistance value on the LCD.
5) If the resistance is less than 40
, the continuity beeper will sound.
Frequency Measurements
1) Ensure that at least 0.1A AC is detectable with an ACA measurement before measuring
Frequency.
2) Set the Function switch to the Hz position.
3) Insert the test leads to the meter as follows: Red lead to “V,Hz,
” terminal; Black lead to the
COM input.
4) With the pointed end of the test leads measure frequency
5) Read the Frequency measurement on the LCD in Hz.
Additional Features
Relative Measurements
1) Press the Zero key and the present measurement will Zero.
2) All subsequent measurements are displayed with respect to the zeroed reading. For example,
if a 20A reading is zeroed and a 30A reading is subsequently measured, the LCD will display
10A.
3) To return to normal operation, press the zero key one more time.
4) Note that Relative mode is not available if the MIN/MAX mode is enabled.
5) Relative mode is not available in continuity or Hz mode.
6) Note that the Zero button is disabled if ohm and continuity or Hz functions are selected.
7) LCD displays relative numerical value without bargraph.
Data Hold
To freeze a reading on the LCD, press the Data Hold key. The HOLD icon will appear and the
measurement will be held on the meter’s LCD. To release the Data Hold function and return the
meter to normal operation, press the Data Hold key again. Data Hold is disabled if ohm and
continuity function are selected.
MIN/MAX Reading Mode
Pressing the MIN/MAX key allows the meter to display ONLY the highest and the lowest readings
encountered. Press the MIN/MAX key once to view the minimum reading, press it again to view
the maximum reading. The LCD will toggle between the MIN and MAX values. Press and hold
MIN/MAX button for more than 2 seconds to return to normal operating mode. Zero function will
be disabled when MIN/MAX is enabled. MIN/MAX is not available in continuity or Hz mode.
