2250 Light – User Manual
The instrument will automatically switch off when it has been in standby mode without
external power for more than 30 hours.
Note 1: If the instrument is powered externally the Standby After parameters are ignored and
the instrument will never go to standby. However, if the instrument is left unused for more than
Standby After time the Standby After setting will overrule the Backlight settings and the
backlight will be switched off.
Note 2: Please use the Display Settings in conjunction with the Power Settings to save power
during measurements and extend the battery operating time.
Hardware version 4 (G4) has an Ext. Power setting, which determines whether the analyzer
automatically switches on and charges the battery when external power is applied or the battery
is just charged. For unattended externally powered measurements (when not using timers), it is
recommended to select the
Switch On and Charge to ensure measurement will restart in case of
temporary power failure.
Hardware versions 1 – 3 have a similar function, but it is a small, manual switch at the back of
the analyzer, behind the battery pack, which you must set. Remove the battery to access the
switch.
When you have made your choices, tap on Power Settings , or on the minus icon , to collapse
