15.5 DIAGNOSTIC INFORMATION
分析诊断信息
The printed circuit board inside the ViscoSense
®
2 controller has a provision for diagnostic indication.
Failures and errors are displayed by a blinking digit or character on a 7 segment LED. Dependent on
the type of failure, error or warning, the viscosity and/or temperature outputs will go to 0, 4 or 20 mA,
or will remain functioning normally.
控制器中的印刷电路板有一个实用的帮助分析诊断失效的规定。
误差和故障通过闪光的数字或者符号在一个
7
片段发光二极管上显示出来。取决于失效，误差或警报
的形式，粘度和
/
或温度的输出将会为
0
，
4
或
20mA;
或者保持正常功能。
If there is no failure, error or warning, the display indicates the state of the program by displaying a
symbol (not blinking) on the display.
如果一切正常，显示器上将会显示指示程序状态的（不闪光跳
动）符号。
The following symbols are displayed during normal operation:
正常操作情形下，将会显示下列符

The decimal point at the bottom of the display is always on after power is on. This point is only
turned off while the ViscoSense
®
is writing to EEPROM, and if no measurement is possible due to
extensive external vibrations.
电源接通后小数点总是在底部显示。如果由于巨大的外部振动导致无法测量，传感器写入电可擦只读
存储器时它才消失。
Normally the ViscoSense
®
2 electronics will try to restart the unit if a faulty situation occurs. However,
if the fault is persistent contact VAF Instruments or your local authorised VAF dealer and give a
detailed description of the problem that occurred and the diagnostic information indicated at the 7
segment LED.
通常如果发生故障，传感器将会重新启动装置。但是如果故障仍然存在，请及时与
VAF
或所在地经

片段发光二极管上显示的帮助诊断资料。
