Summary of Contents for Shimaden TH71A Series
- Page 1 Instruction Manual Preface Thank you for purchasing a Shimaden TH71A/T71A/H71A Series sensor. Please read the instructions carefully and get a good understanding of the contents before attempting to operate this equipment. The instruction manual should be kept in a handy place where the end user can refer to it when necessary.

Type of humidity sensor Probe type (with lead wire 1.5 m) 0 to 10 mV DC/0 to 100% RH Output resistance: 10Ω(linearized output) 0 to 100 mV DC/0 to 100% RH Output resistance: 100Ω(linearized output) 3.
- Page 3 TH71A/T71A/H71A Series Instruction Manual H71A (⌀20) Unit: mm ○ To separate the cover from the base, please loosen lightly the lock screw (+) at the right side and separate the cover from the base by holding the cutout spot (fixed nail) at the upper and lower center of the cover. 5.
- Page 4 (Variation almost parallels to all the measuring ranges.) In case of the error over ±10% RH, please consult your nearest Shimaden agent since a replacement of the humidity sensing part is necessary. 3. Temperature output adjustment (only in the case of TH71A and where a temperature output signal is a voltage output.) There is no need for adjustment since the temperature output has been corrected at the time of the shipment from the factory and almost no secular distortion occurs concerning the temperature sensing part, compared with the humidity sensing part.
