3. OPERATION

3.6.1.3 <3COM>

 OPERATION/PURPOSE

To access Reset - Com, press [SPECIAL] and select <1reset>, <3com>.

Reset - Com clears and sets to default the molbox RFM communications ports

(see Section 3.6.6). This includes:

• COM1 and COM2

Baud rate: 2 400

Parity: Even

Data bits: 7

Stop bits: 1

Terminating characters: <CR>, <LF>

• IEEE-488 (GPIB)

Address: 10

Terminating characters: <CR>, <LF>

3.6.1.4 <4CAL>

 PURPOSE/OPERATION

Use special caution with this reset as critical calibration data may be altered.

To access Reset - Cal, press [SPECIAL] and select <1reset>, <4cal>.

Reset - Cal clears and sets to default the user calibration coefficients for molbox

RFM Reference Pressure Transducers (RPTs) (see Section 5.2). If the molbox

RFM has been recalibrated at any time since its original factory calibration, the

recalibration adjustment was done using these user calibration coefficients. The

RPT cal coefficient defaults are:

• Upstream and downstream absolute RPTs:

Adder 0

Multiplier: 1

Calibration Date: 19980101

• Microrange differential RPT:

Adder: 0

Multiplier: 1

Calibration Date: 19980101

Reset - Cal has NO effect on the reference resistance values used to calibrate

the molbox RFM internal ohmic measurement system (see Section 5.3).

3.6.1.5 <5ALL>

 PURPOSE/OPERATION

To return molbox RFM to the original, as delivered factory condition. Performs the

RESET - SETS, UNITS, COM and CAL functions and resets all other settable

values to defaults.

To access Reset - All, press [SPECIAL] and select <1reset>, <5all>.

Use special caution with this reset as critical calibration data may be altered.
