PREPARATION FOR USE AND INSTALLATION
SECTION 2
PREPARATION FOR USE AND INSTALLATION
2.1 Unpacking and Inspection
Upon receipt, the R1M-A and accessories should be carefully
unpacked and removed from the shipping container.
Separate the units from the packing material and inspect
both the instrument and the accessories for any external
damage.
If any dents, broken, or loose parts are seen, do not use
the equipment. Notify the shipping company immediately
and follow their instructions as to how to proceed.
Check that all items are present. If any items are missing,
notify the shipper if this is a new instrument. If not new,
contact the previous user to locate the missing item(s).
2.2
Preparation for Use
Release the two latches which secure the lid and open the
lid. Remove the power cord and the two test cables which
are stored in the side compartment. If desired, the lid may
then be removed by pushing it to the right.
Set the ‘TEST VOLTAGE’ rotary switch to the desired value,
from 50 V to 500 V and set the ‘OHMS RANGE’ switch to the
anticipated range.
Note that although the ‘OHMS RANGE’ switch is marked from
1 M to 100 G, a 100% over-range capability is built into this
instrument.
Note also, that for resistance values less than 1 MΩ, the only
test voltage that should be used is 50 V. No damage will
occur if a higher voltage is selected, but the readings may
not be accurate. Do not measure resistors less than 50 kΩ
with the R1M-A; it may damage the instrument.
WARNING
SHORTING THE ‘TEST’ and ‘SIGNAL’ LEADS TOGETHER WILL
CAUSE INSTRUMENT DAMAGE.
