Drifting baseline - ERD 500 - ERS 500e - ERS 500 Carbonate - DRS 600 - Drifting baseline - ERD 500 - ERS 500e - ERS 500 Carbonate - DRS 600

If the baseline drifts steadily upward, increase the current setting by 5-10% to reduce the background conductivity. As the background conductivity decreases, the baseline drift should decrease.
