• The primary display shows ---- until you press the

T button and a valid resistance reading is

obtained.

• The high voltage symbol (Y) along with a primary

display of >2 V warns if voltage greater than 2 V

ac or dc is present. In this condition, the test is

inhibited. Disconnect the Tester and remove

power before proceeding.

• If the Tester chirps when you press the T

button, the test is inhibited because voltage is

present at the probes.

5. Push and hold the T button to start the test. The

t icon appears on the lower portion of the display

until you release the T button. The resistance

reading appears on the primary display until a new

test is started or a different function or range is

selected.

When resistance is higher than the maximum display

range, the Tester displays the > symbol and the

maximum resistance for the range.
