Using the two peg method, calculate the difference in level between two points P and Q given the following staff readings: Instrument near P: RP=3.145m, RQ=1.500m. Instrument near Q: R’P=2.740m, R’Q=1

Question 21: Two peg method of testing

• Instrument near P:
  • Staff reading at P ($R_P$): $3.145 \text{ m}$
  • Staff reading at Q ($R_Q$): $1.500 \text{ m}$
• Instrument near Q:
  • Staff reading at P ($R'_P$): $2.740 \text{ m}$
  • Staff reading at Q ($R'_Q$): $1.105 \text{ m}$

Step 1: Calculate the observed difference in level for each instrument setup.
When the instrument is near P
