1.B.3 Press DIAG; “rc 1” will be displayed and the analyzer
will execute this mode calibrating the span value e.g.
1V, 10mV or 100mV.
Microprocessor programming routines will measure and cali-
brate the output limits. This procedure will set the output to
approximately 1% accuracy. Fine tune the recorder output by
following the procedure in step 3.
Step 2
If the 4-20 mA output is used (4 Ω < load < 500 Ω), it is
self-calibrated by selecting the 4-20 mA CAL output with the
recorder output selector DIP switch.
2.A To automatically calibrate "4 mA"
2.A.1 Set the 4-20 mA CAL switch to
ON. Because only one switch
should be on at any one time,
all other switches should be off
while the 4-20 mA CAL switch
is selected.
2.A.2 Press DIAG. The display will show the last diagnostic
mode and the right-most numerical digit will blink.
2.A.3 Enter code 106 using the and keys.
