When testing objects with large capacitance, it may take a considerable amount of time for the charging current to approach zero. Therefore it also may take considerable time before the IR test returns a true resistance reading.
- Page 18 This status message will appear at the HV Waiting Screen if an open Security Circuit is detected regardless of what operation mode the PM15-4A is set to (Normal or Guard). If this message is seen, check the security circuit for loose connections or replace the SX1 plug onto the front panel to close the security circuit.

The PM15-4A will discharge the test object upon test completion. Depending on the size of load capacitance, dangerous voltages may be present at the end of the lead for a few moments. Always ground any high voltage leads before removing leads from test object.

Page 38: Care And Maintainance
5. CARE AND MAINTAINANCE 5.1 NI-MH BATTERY MAINTAINANCE NI-MH batteries have a high self-discharge rate. It is therefore recommended to complete a full charge cycle at least once a week. If the batteries become discharged to the point the unit will no longer turn on under battery power, complete a full recharge cycle by plugging the unit in and leaving it plugged in for 3 hours. - Page 39 5.3.2 Status LED The printer incorporates a LED indicator to report its condition. If there is a fault, the LED will flash in sequence. The fault can be identified by counting the number of flashes. After extensive printing the print head temperature may rise to an unusable level. The Status LED will report when this occurs, and printing will be suspended until the head temperature returns to normal levels.
