Technical Data
Display	Measuring Range
4 x 7 segment 1/2” LED Display Indicator Lights: 4 LED indicators: Status, Alarm, Relay A, Relay B	pH:                    0.00 to 14.00 pH Temperature:    0 to 100°C (32 to 212°F)
Power Requirements	Calibration
Standard:                    98-132 Vac 50/60 Hz, (less than 10 VA) Optional:                     196-264 Vac 50/60 Hz (less than 10 VA)                                    23-26 Vdc (nominal current: 150 mA)	2 point, manual or automatic buffer recognition
Ambient Conditions	Temperature Compensation
Temperature:            -30 to 50°C (-22 to 122°F) Humidity:                   0 to 90% RH non-condensing	Automatic:    0-100°C (32 to 212°F) if probe has temperature sensor
Sensitivity	Stability
0.1% of span	0.1% of span per 24 hours non-cumulative
Control Relays	Test
Number:                   Two Control Relays: Relay A, Relay B Rating:                      5A 115/230Vac, 5A 30Vdc SPDT Bidirectional:            Relays factory preset for bidirectional                                  control can be individually field set                                  for rising or falling pH. On / Off Setpoints:    Field selectable 0.00 - 14.0 pH. Cycle Timer:             Field selectable on and off times 0-600sec Manual Override:      Relay A only: AUTO/OFF/ON Fail- safe:                 Normal or fail safe operation	Display value and analog outputs can be set to any value for testing and diagnostic purposes.
Alarm Relays	Analog Ouput
Number:                   One Alarm Relay Rating:                     5A 115/230Vac, 5A 30Vdc, SPDT Alarm High:              Field selectable 0 -14pH Alarm Low:               Field selectable 0 -14pH Deadband:                Fixed at 2% of full scale Fail-safe:                  Normal or fail safe operation Relay Indicators:      Three individual LEDs indicate	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 represent                             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 0-1mA and 0-5Vdc outputs can be selected                             to track either the pH or the temperature of                             the process
