Lamp Replacement cont’d.
1. Remove the lamp module from the instrument by squeezing the two side tabs on the module inward
while pulling the module out of the instrument. Pull the module away from the instrument until the
in-line power connector is exposed (about 6-8 inches).
2. Unfasten the connector by holding on to the white in-line connector and pulling the in-line
connector apart. When pulling the in-line connector apart, DO NOT hold on to the wires.
3. The new lamp module can now be connected to the instrument using the in-line power connector.
4. Feed the wire back into the instrument being careful that the wire does not get in the way of the
lamp or the lamp holder Z (on instrument). Make sure that the light bulb icon on the back of the
lamp module is upright. Press the module into the instrument until you hear it click firmly into
place.
Note: The side tabs may need to be pressed outward until they click to secure the new lamp module.
5. If the two side tabs on the lamp module do not click the lamp module securely in place, check that
the power wire is not obstructing the lamp module.
6. Turn on the instrument and follow the instructions in section 4.1 to re-calibrate the instrument with
the new lamp module. The instrument must be re-calibrated after lamp module replacement.
7. Resume normal operation.
8.3 Battery
Replacement
The backup of calibration and user preferences requires power. For this reason, the MICRO 100 should
be plugged in (it can be left off) when not in use. If the unit is unplugged from the wall receptacle or the
provided power supply, the batteries in the MICRO 100 will provide the backup power. As these
batteries are non rechargeable and have a finite life, they will need replacement if the instrument is left
unplugged for long periods of time.
It is recommended that the battery replacement be performed at HF scientific. Please refer to the
following section for contact information.
