12. LOOP TESTING
The 47LHZ can provide simulated analog output with the display value manually adjusted. It is called loop test output. It is
convenient to check or calibrate a receiving instrument. The alarm trip functions according to the scaling values during the
loop test.
12.1 LOOP TEST OUTPUT RANGE
-10 to +110% of the display scaling span can be set manually. Setting below -19999 or over 19999 is not available.
e.g. With the display scaling values 0.00 to 100.00, setting manually within the range of -10.00 to 110.00 is available.
The DC output is provided within the range of -5 to +105% of the output span. Output below -5% or over +105% is satu-
rated.
e.g. With the DC output 4 – 20 mA DC, the output can be provided within the range of 3.2 to 20.8 mA DC.
