8: GENERAL MEASUREMENT PROCEDURES
8.1
This section describes general operation of the Meter. When making
measurements of any type, refer to this section. Always prepare the Meter
for use by reading and following the Preparation for Use section of this
manual (Section 7.0).
WARNING!!!
THE MODEL 9310-A IS INTENDED FOR USE ONLY BY PERSONNEL
TRAINED IN THE PROPER SAFETY PROCEDURES AND WHO CAN
RECOGNIZE SHOCK AND SAFETY HAZARDS.
8.2 High Voltage Measurements
CAUTION:
Always observe the following rules and procedures when making
measurements in high voltage circuits. Voltage greater that 40VDC or 25VAC
may create a serious shock hazard. Never use this Meter on circuits with
CAT III voltages higher that 600VRMS. Treat any unknown voltages as
though they were high voltage.
WARNING!!!
IF IT IS NOT POSSIBLE TO TURN POWER OFF TO THE EQUIPMENT,
THEN THE USE OF A LINEMAN’S GLOVE CONFORMING TO
ASTM D120 IS REQUIRED.
For maximum safety, turn the equipment or voltage source off before
connecting the test leads. Make certain that no capacitors in the
circuit being tested remain charged to a high voltage.
Set the Meter to the appropriate AC or DC Voltage range. If the voltage is
unknown, set the Meter to the Auto (default) or to the highest range.
NEVER CHANGE RANGES WITH POWER APPLIED TO THE CIRCUIT.
8.2.1 To connect the leads and take the measurement proceed as follows.
If you ARE NOT using a Lineman’s Glove
While holding the insulated test lead probe body, touch the test prod tips
to the circuit being tested. If no voltage is present, it is safe to use the
supplied alligator clips to connect to the points to be measured. If a
voltage is found, check the equipment to make certain that all power is
off and all capacitors are discharged.
