TROUBLESHOOTING

The

PortaSens II

is a self contained instrument that does not require regular service.

Only periodic calibration should be necessary to maintain proper operation. Should a problem
arise with the unit, there are a few tests that can be done to determine the source of the problem.

A: SENSOR LED NOT FLASHING

1.   If the instrument is not charging and is not running, the sensor LED will flash about every 3
      seconds. If the sensor LED is not flashing both batteries are fully discharged. Replace the
      primary D cell and place the unit on charge for 24 hours.

B: DETECTOR DOES NOT START WHEN SWITCH IS PRESSED

1. Check to see that a fresh battery is installed. Both the primary and secondary batteries must

be discharged for this problem to occur. Plug the charger into the connector. Wait 5-10
minutes and then retry. If the instrument still doesn’t start, contact ATI for service.

C: LOW BATTERY WARNING OCCURS QUICKLY AFTER EXTENDED CHARGE

1. Check battery charger under load by connecting an 12 ohm resistor across the charger and

measuring the voltage. Voltage should be approximately 6 volts.

2. If charger is OK, battery is defective. The unit may be operated off the primary “D” cell

without an operational rechargeable battery. Unit must be returned to ATI for rechargeable
battery replacement.

D: DETECTOR DOES NOT RESPOND TO GAS

1. Run the Response Test outlined in this manual. If the instrument does not respond, the

sensor is either depleted or has become fouled. Replace sensor or return to ATI for service.

E: PUMP TROUBLE ALARM DISPLAYED ON THE LCD

1. The pump trouble alarm will occur if the pump control circuit cannot maintain RPM. The

cause might be a plugged inlet filter or inlet wand. If an extension is used, check that the
tube is clear. Replace inlet filter as needed.

F: CONCENTRATION ALARM REMAINS ON FOR AN EXTENDED PERIOD

1. If the sensor has been exposed to a very high gas concentration (% levels), it can take a

relatively long time to recover to zero. Simply leave the unit running for a few hours and the
condition should clear itself. If the condition does not clear after 6 hours of operation, the
sensor may have been damaged. Replace the sensor or contact ATI for service.

G: EXTERNAL FLOWMETER INDICATES NO FLOW, EVEN WITH PUMP RUNNING

1. Check filter assembly and replace if clogged.

2. Check that the manifold screws are secure and that the inlet fitting screwed into the manifold

is tight. A loose manifold or fitting could cause air to be drawn into the pump from around the
manifold without flowing through the inlet wand.
