16. ***RATED CIRCUIT-TO
-GROUND VOLTAGE: 1000V AC/DC Max.
* Accuracies specified are for the 260 in a horizontal position.
** Responds to the average value of an AC current, and is calibrated to indicate
the RMS value of a pure sine wave.
*** Per ANSI C39.5 April 1974: “The specified voltage with respect to ground,
which may be safely and continuously applied to the circuit of an Instrument.”
1.9 Definition Of Accuracy
The voltage and current accuracy of this Instrument is commonly expressed as a
percent of full scale. This should not be confused with accuracy of reading (indica-
tion). For example, +2% of full scale on the 10 volt range allows an error of 0.20V
at any point on the dial. This means that at full scale, the accuracy reading would
be 2%, but at half scale it would be 4%. Therefore, it is advantageous to select
a range which gives an indication as near as possible to full scale.
1.10 Safety Considerations
This Operator’s Manual contains cautions and warnings alerting the user to haz-
ardous operating and service conditions. This information is flagged by CAUTION
or WARNING symbols throughout the publication, where applicable, and is de-
fined on the inside front cover under “Notes and Safety Information.” Adhere to
these instructions in order to ensure the safety of operating and servicing person-
nel and to retain the operating conditions of the Instrument.
1.11 Audio Alarm
The 260 Audio Alarm transducer will emit an audio sound when the continuity of a
circuit being tested is completed.
No Circuit Continuity Tests are to be made with electrical power “ON.” Turn “OFF”
all electrical power.
