Cold Junction
Compensation
Internal compensation with the ability to manually adjust values, External Input for
compensation, External CJC value specified
Input Resolution 0.0015% (16 Bit ADC)
Input Impedance Current loop resistance: 10 ohms, use ±0.1% external resistor. Volts >1MΩ, all other 10MΩ
Source Impedance T/C and RTD: 100 ohms per lead maximum. (A single point cal on Slot A will improve
accuracy for a lead resistance above 10 ohms).
Square Root Extraction Available as standard on every input type
Sensor Compensation Single point and Dual point
Input Sampling Rate Recorder has 2 available slots with up to 8 analog inputs each; the input sampling rate is
dependent on actuation type.
All Inputs: 100mS (10Hz), 200mS (5Hz), 500mS (2Hz)
Fast Sampling: 20mS (50Hz) - mA, mV, Volts and Ohms only
Scales, Linear &
Logarithmic
Normal and Scientific notation
Decimal Point automatic or programmable
Engineering units, user definable (10 characters)
Logarithmic Decade limits: -38 min, to +38 max, (recommend up to 20 decades on one
screen to ensure clarity)
Input Isolation 300VAC channel-to-channel, channel-to-ground
Noise Rejection
(at 50/60Hz) +/-2%
Common mode: 2Hz = -120dB, 5Hz = -120dB, 10Hz = -120dB
Normal Mode: 2Hz = -85dB, 5Hz = -80dB, 10Hz = -48dB
Specification Logging
Logging Method Sample, Average, Min/Max - can be set independently per pen
Logging Types Continuous, Fuzzy
Logging Rate From 20 msec. to 60 hours per pen
Fuzzy Logging A secure data storage technique which delivers data compression ratio of 100:1 or more;
self teaching, storing the data at a variable rate to match the process
