Zn-Thx21-S - Omron ZN-DPX21-S Series User Manual

(6) Battery backup
The product has a battery backup function (two AAA batteries). Using rechargeable nickel
metal hydride batteries or alkaline batteries prevents failure in communications via LAN and
recording operations in case of a power failure or power shutdown.
* The unit can operate up to approximately 2 hours with batteries only. However, the battery
life varies subject to measurement environment, conditions, and type or performance of the
batteries.

1.1.2 ZN-THX21-S

(1) High-precision Air Thermo Sensor
Air Thermo Sensor Head ZN-THS1-S allows for the accurate measurement of the
temperature and humidity with a temperature resolution of 0.1°C (at 25°C) and humidity
accuracy of ±2.5 %RH (25°C, 10 to 85 %RH). The ZN-THS1-S contributes to the
improvement for better quality and management of temperature and humidity through
accurate measurement.
(2) Network connections
By connecting the Thermo-Humidity Stations to a PC via LAN cable and using the PC
software Multi Data Viewer Light, the measured values obtained from one or more
Thermo-Humidity Stations can be moved to the PC, and the settings of a Thermo-Humidity
Station can be checked or changed and start/stop recording of the Thermo-Humidity Station
can be specified. (Refer to " Multi Data Viewer Light Software Manual" for details.)
Furthermore, use of the optional Wave Inspire ES environmental visualization software allows
for real-time centralized control online.
(3) Recording with SD memory card
The measured data can be recorded in the Thermo-Humidity Station while communicating via
LAN with host devices. Up to approximately 8500 data items can be accumulated in the
internal memory of the sensors (except for an Air Particle Sensor), and the data recording in
the Thermo-Humidity Station unit can be continued even at an emergency network failure. The
data accumulated in the internal memory can be output to the SD memory card as a CSV file
without stopping measurement and the data can be managed by a PC.
(4) Graphical display software
The data recorded in a PC with the logging tool and the data output to the SD memory card
with the Thermo-Humidity Station can be displayed as graphs by the PC software (offline).
The data items of different periods can be combined, the data items of temperature and
humidity can be displayed side by side, and the data across multiple Thermo-Humidity
Stations can be displayed side by side. (Refer to " Multi Data Viewer Light Software Manual"
for details.)
(5) Alarm output
The Thermo-Humidity Station comes standard with the alarm output terminals. The alarm will
output when measured temperature or humidity exceeds upper or lower limit. This function
allows quick response to the problem by visualizing the limit of temperature and humidity.
(6) Battery backup
This product has a battery backup function (two AAA batteries). Using rechargeable nickel
metal hydride batteries or alkaline batteries prevents failure in communications via LAN and
recording operations in case of a power failure or power shutdown.
