NOTE:
If using a 2850 Conductivity/Resistivity Sensor Electronics in conjunction with your 9900, the 2850 must
be set for the custom cell constant or the actual probe cell constant and the 9900 set for a 1.0 cell constant.
INPUT Menu
Enter string up to 13 characters (optional).
Default = COND/RES
Enter cell constant of sensor. Select 20.0, 10.0, 1.0, 0.1, 0.01, or CUSTOM.
Default = 1.0 (See NOTE below)
Enter the precise cell constant from the certi
fi
cate provided with your sensor, or from the information
label on the sensor. Shown if CELL CONSTANT = CUSTOM. (See NOTE below)
Select °C, °F.
Default = °C
Select
μ
S, mS, PPM, PPB, KOhm, or MOhm.
Default =
μ
S.
NOTE:
In USP Relay Mode, TEMP COMP must be set to NONE and Unit Of Measure must be set to
μ
S.
If the COND UNITS selection is PPM or PPB, set the ratio of Total Dissolved Solids to
μ
S.
Default = 0.50
Dampens display, output and relay response rates.
Select Low, Med, High, or OFF. (See discussion in Appendix)
Default = OFF
Select temperature compensation (NONE, LINEAR, PURE H2O). Default = LINEAR.
NOTE:
In USP Relay Mode in Conductivity, Relay Source must be set to COND, TEMP COMP must be
set to NONE and Unit Of Measure must be set to
μ
S.
For LINEAR or PURE H2O temperature compensation, select a % per ºC slope.
Maximum slope setting is 9.99 % per ºC. Default = 2.0
(If Temperature Compensation setting is NONE, this item will not be displayed)
