PREPARATION FOR USE

This section contains instructions for preparing the new Instrument for use.
Also included are unpacking and inspection procedures, warranty, shipping,
and power source requirements.

2.1

Unpacking And Inspection

Examine the shipping carton for signs of damage before unpacking. If the
carton is in good condition, unpack and inspect the Instrument and packing
materials for possible damage incurred during shipment. If damage is noted,
notify the carrier and supplier and do not attempt further use of the Instru-
ment. If the Instrument appears to be in good condition, read the Operator’s
Manual in its entirety. Become familiar with the Instrument as instructed in the
manual, then check the electrical performance. Also check to see that all fur-
nished items and accessories are included (Table 1-1). Save the shipping
carton and packing material for future storing or shipping of the Instrument.

After unpacking the Instrument, a 1.5 V battery and two 15 V batteries may be
found in separate envelopes in the box with the Instrument and test leads.
Two alligator clips for the test leads are in a polyethylene bag. (See Section 5
for instructions on how to open the battery compartment and install the bat-
teries.)

2.2

Warranty

The Simpson Electric Company warranty policy is printed on the inside front
cover of this manual. Read it carefully before requesting any warranty repairs.

NOTE: For all assistance, including help with the Instrument under warranty,
contact the nearest Authorized Service Center for instructions. If  necessary,
contact the factory directly. Give full details of any difficulty, the Instrument
model number, series number and date of purchase. Service data or ship-
ping instructions will be mailed promptly. If an estimate of charges for non-
warranty or other service work is required, a maximum charge estimate will
be quoted. This charge will not be exceeded without prior approval.

2.3

Shipping

Pack the Instrument carefully and ship it prepaid and insured.

2.4

Power Source Requirements

There are three batteries in the ohmmeter circuits. One is a NEDA 13F cell
that furnishes 1.5 volts for all ranges except RX10,000 range. Two NEDA 208
cells furnish 30 volts for the RX10,000 range. Weak batteries should be re-
placed promptly . Replace with the same type batteries as supplied with the
Instrument. (See Table 1-1.)
