25 Leica EG1150 H – Paraffin Embedding Station
• The heaters become active and the LEDs indicate the values last set.
The target value LEDs for the heating areas (1, 3, and 4 in
Fig. 18 ) flash
quickly for the duration of the heating phase (cf. "Display of the heating
intervals").
The LED for the paraffin reservoir (2 in Fig. 18 ) flashes in 1-second inter-
vals and thereby indicates the intensified heating of the paraffin reser-
voir (for 4 hours).
If temperature settings are modified during the heating phase, the in-
strument will store the new settings and the heating phase will then
correspondingly take longer.
• Fill the paraffin reservoir with paraffin.
5.2 Switching the instrument on
• Activate the standby switch (left-hand side, next to control panel)
(see Fig. 15, 17 ).
• All LEDs of the operating panel light up briefly and the installed software
version is shown on the display for around 2 seconds.
All displays go out, the unit changes to standby mode.
The green LED in the ON/OFF button indicates that the instrument is
ready to operate.

• Press the ON/OFF button down for approx. 2 seconds to

Prior to leaving the factory, the Leica EG1150 H is tested thoroughly under laboratory condi-
tions. For this reason, you will find a small quantity of clean, hardened paraffin. You can work
with this paraffin without any problem.
The unit's normal operating mode is STANDBY/ON; i.e. switch on/
off with the ON/OFF key only.
Use the standby switch only if the device is to be switched off for
an extended period.
