Figure 5-30.—Effects of resistance on the rotation angle in low range.
MEDIUM 1 RANGE.—The medium 1 range is designed to test for resistance values between 50
W
and 10KW. Figure 5-31 shows the signatures for a 50W resistor, a 1KW resistor, and a 10KW resistor
using the medium 1 range. Resistors that are smaller than 50W display a signature that is almost a vertical
line. A 1KW resistor causes a change in the angle of rotation of 45º, whereas the display of a 10KW
resistor shows only a slight rotation. Resistance values under test higher than 10KW produce a signature
with such a small rotation angle that it almost appears to be a horizontal line.

Q-11. Medium 1 range is designed to check what resistance values?
MEDIUM 2 RANGE.—The medium 2 range is designed to test for resistance values between 1K
W
and 200KW Figure 5-32 shows the signatures for a 1KW resistor, a 15KW resistor, and a 200KW resistor
in the medium 2 range. Resistance values that are smaller than 1KW will appear to be almost a vertical
line. A 15KW resistor causes a change in the angle of rotation of 45º, whereas the display for a 200KW
resistor shows only a slight rotation. When resistance values being tested are higher than 200KW, the
displayed signature that they produce will have such a small rotation that it appears to be almost a
horizontal line.
