 ± 0.3 % of Full Scale   ± 1.8 % of Full Scale
 i) Band gap temperature sensor for Temperature ii) Capacitive polymer sensing for Relative Humidity
 Standard 1 meter, can extend upto 15 m on requrest
 Upper : 4 Digit, 0.56” (13 mm), 7 segment RED L.E.D display for Humidity
 Lower : 4 Digit, 0.56” (13 mm), 7 segment RED L.E.D display for Temperature
 TD1 & TD2 for Time Delay, RL1 & RL2 for Relays, TX & RX for Communication,
 PRG to show ‘User’ in Programming mode, DEW to show Lower display shows ‘Dew point’
 Two independent set points, one each for RL1 & RL2 with programmable Latch & Non-Latch facility
 0 To 10, Independent setting for RL1 & RL2
  LO - HI, HI - LO, LO - Very LO, HI - Very HI; programmable by user 
 0 To 9999 sec, Independent setting for RL1 & RL2 to operate after the ‘Process Value’ crosses ‘Set point Value’
 1 NO - C - NC Relay contact Rated 230 VAC/5A for RL1 & RL2
 RL1 operates for Humidity, RL2 operates for Temperature
 In ‘Under’, ‘Over’ OR ‘Open’ condition i.e. fault condition, Relay can be made OFF or ON; programmable by user
 Setting by 4 keys on front panel i.e. ‘SET / NEXT’, ‘UP’, ‘DOWN’ & ‘ DEW / BACK’
 NOTE : If you press ‘ DEW / BACK’ key, Lower Display shows ‘Dew Point’
 i) By Display : Sensor ‘Break / Open’ shows ‘oPEn’ Indication
 ii) By Retransmission current O/Ps : Up scale current : 21 mA, Down scale current : 3 mA; programmable by user
 i) 2 No, 4 - 20 mA OR 20 - 4 mA programmable with max load 750 ohms for Temp & Humidity
 ii) Range: - 999 To 9999, Low range & High range : Anywhere in the range (High range > Low range)
