*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.”
1.10 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 (indi-
cation). 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.
1.11 Safety Considerations
This Operator’s Manual contains special caution and warning symbols which
alert the user to hazardous operating and service conditions. These symbols
appear throughout this publication where applicable, and are defined on the
inside front cover of this manual under NOTES AND SAFETY INFORMATION.
Please adhere to these instructions to ensure the safety of operating and servic-
ing personnel and to retain the operating conditions of the Instrument.
1.12 Audio Alarm
The 260-8P Audio Alarm is a transducer which will emit an audible sound when
the operator of the Instrument intends to quickly determine the continuity of a
circuit.
NOTE:
Not protected by Electronic Overload Protection System.
Do not make Circuit Continuity Tests with electrical power “ON”. Turn “OFF” all
electrical power.
