7.7.5 If the displayed value is less than “200” (decimal point not

shown), a more accurate reading may be obtained by setting

the RANGE switch to a lower range. Rotate the RANGE switch

to the next lower position and observe the reading on the LCD

display. If the RANGE switch is already on the lowest position

(i.e. 200 Ohms), no greater measurement resolution can

be obtained.
