Before Using this Gauge
• Before using the EG-225, remove the rubber ring which is used
to hold the spindle in place.
• Over-discharge can occur during shipment.
If the EG-225 is to be used with both battery and AC power,
first charge the battery sufficiently. (The recharging method is
described in Section 4, power supply connection.)
• When using the EG-225 for the first time, press the power switch
and reset switch simultaneously to perform a system reset.
• When the voltage of the internal rechargeable battery falls be-
low a reference level (approx. 4.7V), “B” will appear on the LCD
display. If operation is continued in this condition, when the
voltage falls below approximately 4.6V, “B” will appear on the
LCD display and the power will switch off automatically. In this
condition, if the power is switched on once again, “B” will ap-
pear for approximately two seconds and the power will be
switched off once again. If “B” appears, the battery should be
recharged. (Do this with the power switched off.)
In addition, when the battery is fully discharged, even if the
power is switched on, nothing will appear on the LCD display.
In such case, after charging the battery, press the power switch
simultaneously with the reset switch to perform a system reset
before beginning measurements.
