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.
