2. SAFETY PRECAUTIONS

WARNING:

1. This instrument is designed to

accept low level signals sup pli ed
by standard thermocouples. Under
NO circumstances should the input
voltage exceed the speci fied 50V
RMS.

2. To prevent ignition of a hazardous

atmosphere, batterie s must only be
changed in an area known to be
nonhazardous.

CAUTION:

1. Do not use or store this instrument

in microwave ovens or any
abnormally hot or cold areas.

2.

leak and cause damage to unit.

DANGER:

1. Voltages present at the

thermocouple may also be present
at the battery terminals. Always
disconnect the thermocouple
when changing batteries.

150 hours remaining.

Selected settings are stored in
memory and will remain in memory
even after power is turned off, or
while batteries are being replaced.

1. Before changing ba ttery, turn
instrument off and disconnect
