Analog Outputs
Non-isolated 0-1 mA, 100 ohms maximum load
Non-Isolated 0-5 VDC, 1000 ohms minimum load
Isolated 4-20 mA, 800 ohms maximum load
Output is isolated from the input, the
ground, line power and all other outputs.
Range Expand Analog outputs can be scaled to rep-
resent any segment of the instrument
scale, minimum of 10% of full scale.
Output Hold Analog outputs are placed on hold
when the instrument is in menu mode.
Temperature The 0-1 mA and 0-5 VDC ou tputs
can be selected to track either the pH
or the temperature of the process.
Calibration 2 Point
Sensor to Controller Distance
Differential R60 Series Differential pH Probe: maximum
distance 3000 feet (914 m)
Combination 500 Series: maximum distance 25 feet (7.62 m)
Temperature Compensation
Automatic 0-100°C (32 to 212°F) if probe has temperature
sensor.
Diagnostics
Invalid Entries Identied by ashing LEDs
System Error Two color STATUS LED indicates system sta-
tus. Green no fault, Red system fault. Scroll to
Status in Menu to determine fault code. Refer
to Manual for probable cause and remedy.
Alarm Relay Alarm relay can be enabled to activate upon
high and low process values and memory loss.
Test Display value and analog outputs can be set to
any value for testing and diagnostic purposes.
Safety & Security
Operator Password protected (activated by DIP switch)
