MAX 4000 PLUS ELECTROMETER 15
10.2 Can’t Get Out of Charge Mode or Rate/Charge Mode
Upon completion of a charge collection in the Charge mode or Rate/Charge mode, the
START/RESET button must first be pressed to reset the display before other buttons will
function.
10.3 No Response
If the system does not respond to any of the buttons, use the external reset switch. See page 5
for details.
10.4 Avoiding Electromagnetic or Other Interference
If the MAX 4000 Plus causes interference with other equipment, attempt to correct the
interference by:
• Increasing the separation between equipment.
• Connecting the power supply cord into a different grounded AC outlet or into a circuit
controlled by a different circuit breaker.
10.5 Low Battery
The MAX 4000 Plus contains 1 rechargeable sealed lead-acid battery with a life of about 6-8
hours. When the battery is at 15% of capacity, “RECHARGE BATTERY” will appear on the display.
If the battery becomes low during a charge collection, the screen will alternate between
“RECHARGE BATTERY” and the status of the collection. The collection process will not be
interrupted.
The MAX 4000 Plus will also operate with the charger plugged into a wall outlet. Re-charging
the battery takes 6 - 8 hours. The MAX 4000 Plus may be continually charged when not in use
with no detrimental effects to the internal battery.
The MAX 4000 Plus will shut off automatically if it is not plugged into the wall charger and is
left unattended for more than 3 hours.
10.6 Threshold Mode - False Triggering
Using threshold start and stop values close to that of the system noise may cause erratic
behavior and false triggering when performing threshold collections. Zero the system, (see
page 7) and/or increase the threshold values to levels above the system noise, (see page 6).
The MAX 4000 Plus will not power ON after a long period of inactivity. (non-use)
To ensure long-term performance of the internal battery, it is recommended to fully recharge
the MAX 4000 Plus electrometer at least every 4 months.
