General Information 1-4 Instrument Care and Preventive Maintenance
Site Master User Guide PN: 10580-00252 Rev. K 1-5
ESD Caution
The Site Master, like other high performance instruments, is susceptible to electrostatic
discharge (ESD) damage. Coaxial cables and antennas often build up a static charge, which
(if allowed to discharge by connecting directly to the instrument without discharging the
static charge) may damage the Site Master input circuitry. Instrument operators must be
aware of the potential for ESD damage and take all necessary precautions.
Operators should exercise practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices,
equipment, and practices. Because these apply to the Site Master, it is recommended that any
static charges that may be present be dissipated before connecting coaxial cables or antennas
to the Site Master. This may be as simple as temporarily attaching a short or load device to
the cable or antenna prior to attaching to the Site Master. It is important to remember that
the operator may also carry a static charge that can cause damage. Following the practices
outlined in the above standards will ensure a safe environment for both personnel and
equipment.
Battery Replacement
The battery can be replaced without the use of tools. The battery compartment is located on
the lower left side of the instrument (when you are facing the measurement display). To
remove the battery:
1. Slide the catch toward the bottom of the instrument.
2. Pull the top of the door away from the unit.
3. Lift out the battery door.
4. Remove the battery pack from the instrument by grabbing the battery lanyard and
pulling out.
Replacement is the opposite of removal. The battery key side (slot below the contacts) should
be facing the front of the unit and slide in first.
Note
When inserting the battery, the battery label should face the back of the instrument
and the guide slot on the battery should be below the contacts. If the battery door
does not latch closed, the battery may be inserted incorrectly.
