0 - 1999mV with 1mV resolution.
Display:
3 1/2 digit LCD displays.
Indicators:
LED lights indicate set point operation, pulse, flow,
configuration and calibration status.
Calibration:
All calibration parameters are programmed into non-
volatile memory.
Electrode:
BNC, external of housing.
Temperature:
Manual compensation selected in the configuration
menu if in pH mode. Temperature range from 0 to
100
o
C. Automatic compensation possible with a
TP-100 electrode connected.
Signal output:
4-20mA software configuration over range 0-14pH or
0-1000mV. Current output fully isolated. Maximum
termination impedance for 20mA is 1000 Ohms.
Control range:
Set point range 0pH to 14pH or 0 to +1000mV
Pulsed output:
Selected for Relay1 through setup program. Pulse
width adjusts automatically to suit dosing require-
ments. On time varies from continuous to minimum 1
second. Pulse interval increases / decreases to fur-
ther fine-tune a dosing cycle.
