4. Press  once to shi display to ohms mode (Ω).
5. Press the Yellow , then the Gray  buon within ½ second. The message  will be
displayed in the LCD. (See Figure 8)
6. Press the Yellow RESET buon to complete low range (0.1 to 10 ohm) calibraon. The  mes-
sage will automacally be cleared when  is pressed. (See Figure 8)
7. Press the Green  buon. Indicated resistance should be 1.02 (±0.02) ohms as shown in
Figure 8. Press  to clear the display. NOTE: If 1.02 (±0.02) ohms is not displayed, repeat
