Grounding either of these inputs could damage power reference
oscillator and/or power supply.
(2) Grasp power reference oscillator assembly firmly, and remove four screws which
secure it to power meter chassis.
(3) Tilt power reference oscillator assembly to gain access to circuit board
underneath metal cover, and adjust A8L1 (FREQ ADJ) (fig. 5) to obtain a 50.00 MHz
