5.3.4.7. Recorder Offset
If necessary, a recorder offset can be introduced into the analog output voltages. This can be
used to bias the output voltage or current
used to bias the output voltage or current
10%. It is intended for older design chart recorders
that cannot show slightly negative readings. It can also be used to bias the input to a datalogger
to offset small external ground loop voltages that are sometimes present in monitoring systems.
To set the recorder offset, press SETUP-RANGE-OFFS and enter the offset voltage desired in
percent. The recorder offset will bias both the recorder and DAS analog outputs.

5.3.5. Password Enable
If passwords are enabled, one of the values shown in Table 5-6 are required to calibrate or setup
the instrument. If the 512 password is known, only calibrations can be performed. If the 818
password is known, the SETUP mode can be accessed. The 101 password can be used to enter
both calibration and SETUP menus. A list of passwords is in Table 5-6.

5.3.6. Time of Day Clock
The instrument has an internal time of day clock. The time of day can be set by pressing SETUP-
CLOCK-TIME and entering the time in 24hr format. In a similar manner the date can be entered
by pressing SETUP-CLOCK-DATE and entering the date in a dd-mmm-yy format. If you are
having trouble with the clock running slow or fast, the speed of the clock can be adjusted by
selecting the CLOCK_ADJ variable in the SETUP-MORE-VARS menu.

5.3.7. Diagnostic Mode
The M200AH Diagnostic Mode allows additional tests and calibrations of the instrument. These
features are separate from the TEST functions because each DIAG function has the ability to
alter or disable the output of the instrument. While in DIAG mode no data is placed in the DAS
averages. Details on the use of Diagnostic mode are in Section 9.1.3.
