normal measurement mode.
Parameter P2 (Electrode Constant ‘K’ Selection)
1. From the P2 menu, use the CAL or the M+/RM keys to select the desired electrode constant
(0.1, 1.0, or 10). The default setting is K=1.0.
2. Momentarily press MODE to move to the next parameter (P3), or press ENTER to return to the
normal measurement mode.
