Answer
26,000 V, 22,000 V, 4,000 V
Work Step by Step
The upper limit is the measurement + tolerance, that is,
$$
24,000 +2000= 26,000\ V
.$$
The lower limit is the measurement - tolerance, that is,
$$
24,000 -2000= 22,000\ V
.$$
The tolerance interval = upper limit-lower limit, that is,
$$
26,000\ V- 22,000\ V= 4,000\ V
.$$
