2-2 General Specifications
2-2. Performance specifications
A. Performance in ppm mode
- Linearity : ±0.05 ppm or ±0.8% FS,
whichever is greater
- Repeatability : ±0.05 ppm or ±0.8% FS,
whichever is greater
- Accuracy : ±0.05 ppm or ±0.8% FS,
whichever is greater
B. Performance in ppb mode
- Linearity : ±1 ppb or ±0.8% FS,
whichever is greater
- Repeatability : ±1 ppb or ±0.8% FS,
whichever is greater
- Accuracy : ±1 ppb or ±0.8% FS,
whichever is greater
C. Performance in Temperature
- Linearity : ±0.3ºC
- Repeatability : ± 0.1ºC
- Accuracy : ±0.3ºC
Note on performance specifications:
The specifications are at reference temperature
and with simulated inputs, because the
DO202G can be used with many different
sensors with their unique characteristics.
The following tolerance is added to above
performance.
mA output tolerance : ± 0.02 mA of
"4 - 20 mA"
D. Ambient temperature
Operating temperature -10 to 55ºC
(10 to 130ºF)
Storage temperature -30 to 70ºC
(-20 to 160ºF)
E. Humidity
10 to 90% RH non-condensing
F. Housing
Cast aluminum housing with chemically
resistant coating, cover with flexible
polycarbonate window. Case color is off-white
with moss green cover. Cable entry is through
two polyamide cable glands. Cable glands are
provides for wiring up to 2.5 mm.
G. Environmental protection
IP65, NEMA 4X.
H. Mounting
Pipe, wall or panel mounting using optional
hardware.
I. Data protection
EEPROM for configuration; Lithium battery for
clock.
J. Watchdog timer: Checks microprocessor.
K. Autoreturn
The transmitter returns into measuring mode
automatically when no keystroke is made for 10
minutes.
L. Operation protection
All three levels can be protected by a user
programmable 3 digit password
M. EMC Conformity standards ,
EN 61326-1 Class A, Table 2
(For use in industrial locations)
EN 61326-2-3
EN 61326-2-5 (Profibus communication may be
influenced by strong electromagnetic field.)
CAUTION
This instrument is a Class A product, and it is
designed for use in the industrial environment.
Please use this instrument in the industrial
environment only.
N. Explosionproof type
Refer to Control Drawings.
