Pump
The Pump function turns the pump on and off.
The detector is turned off when you turn the pump off. This prevents the detector
from being damaged when there is no sample flowing through the detector.
When the pump and the detector are off, the meter display will continue to read
normally but the instantaneous reading is at 0.0. Turn the pump and detector off
when concentration measurements are not necessary, and the 2020ppbPRO will
only be used for setup or reviewing data. By operating the instrument with the pump
and detector off when you do not need them, you will conserve the battery and
ultraviolet (UV) lamp.
To turn the pump on:
1.
Press the MENU soft key, “Unit Setup”, press SELECT, “Pump”, press
SELECT, “On”, then press SELECT.
