Arizona Jerome 631-X operation manual Sample Mode, Accuracy at MID-RANGE

Page 14

Sample Mode

This is the standard operation mode and is used for optimum accuracy.

Press the power ON button. The LCD displays 000.

Disregard the LCD's initial momentary readings.

Recharge or replace the battery pack if the LO BAT indicator REMAINS ON, see page 17 and/or page 21 if necessary.

Allow a 1-minute warm up before beginning the next step to ensure the instrument's electronics have stabilized.

Press the SAMPLE button.

During the sampling cycle, the bar (or bars) shown on the LCD indicates the current percentage of sensor saturation. (Refer to “LCD Codes” on page 10 for code descriptions.)

The length of the sample cycle depends on the concentration of hydrogen sulfide.

At the end of the sampling cycle, read the LCD.

The number shown on the digital meter is the hydrogen sulfide concentration in ppm.

As the instrument auto-ranges, the decimal point moves to the correct position to show the concentration.

The value remains displayed until the next sample is taken. The digital meter will then automatically zero before displaying the next sample value.

When elevated readings are detected:

Confirm the reading by taking an additional sample.

Install the zero air filter and verify that the readings reduce to zero or very near zero. Remove the filter and sample the location again to verify that elevated reading do exist.

When the sensor is completely saturated, the LCD displays .8.8.8 instead of a value. No further operation is possible until sensor regeneration is performed. (Refer to “Sensor Regeneration” on page 12.)

Press the power OFF button when not in use.

Note: The Jerome 631-X operates approximately six (6) hours on a fully charged battery.
