4.1.8 PASS CODE: This is a very useful & important feature, it allows one to enterthe calibration factor to obtain
expected dose rate. Since theunit is calibrated at factory, user is advised not to disturb the calibration. This is tobe
changed only ifuser intends to re-calibrate the unit.
If you want to change theCalibration factor, use increment or decrement keys set for PASS CODE 90.Then press PROG

CHAPTER -V
CALIBRATION
PRE CALIBRATION
This unit is already having a micro-controller loaded with look-up tablecontaining calibration data (i.e., cps Vs dose
rate tables).In pre-calibration, one cancheck by feeding tail pulses to the unit after isolatingthe detectorfrom the
circuit. Unit display indication will show corresponding dose rate which should confirm to the look-up tabledata.
However each unit may require certain amount of recalibration check in the presence of source calibration is
given inthefollowing paragraph.
SOURCE CALIBRATION
This unit namely Radiation Survey Meter Type : RM701N has been calibrated at Radiation standards and
calibration Lab ( RS& CL) of Nucleonix Systems (P) Ltd., situated at their works.
Before calibration with source, set the calibration factor to 1.000 & save thesettings. No select R/hr asunit of
measurement of doserate. Now place theinstrument in the source beam such that detector is perpendicular to the
beam axis asshown inbelow figure.

Note: CRC - 2 camera having CO60 standard supplied by B.A.R.C Mumbai.
The observed doserates have been to be written +/-15% of the expected doserates for CO60
In case they do not fall within the expected accuracy, then adjust calibration factor so that entire readings will be within
+/-15% of expected doserates.
Once calibration factor is set, make below measurements.
In these readings arefound to be within +/-15%, then expected doserates then unit calibration is said to be complete.
When the manual is dispatched to the customer, calibration factor is to be mentioned below and also saved in the
instrument program.
Note: This instrument will show the constant reading above the 10 R/hr indicating the OVR in the 16x2 Display
upto 200 R/hr.
