Measurement Limits
The protection circuitry of the multimeter can prevent damage to the instrument and
protect against the danger of electric shock, when the Measurement Limits are not
exceeded. To ensure safe operation of the instrument, do not exceed the Measurement
Limits shown on the front panel, it is defined as follows:
Main Input Terminals Measurement Limits
The
Input and
COM
Input terminals are used for voltage, resistance,
continuity, frequency (period), capacitance, diode, and temperature test measurements.
The Measurement Limit is defined for these terminals:
Input to COM Input Measurement Limit
The measurement limit from
Input to
COM
Input is 1000 VDC or 750
VAC, which is also the maximum voltage measurement. This limit can also be
expressed as 1000 Vpk maximum.
Current Input Terminal Measurement Limits
The measurement limit from
10A
input terminal to
COM
Input terminal is 10 A (DC
or AC).
The measurement limit from
μA m
A
input terminal to
COM
Input terminal is 600 mA
(DC or AC).
Note that the current input terminals will always be at approximately the same voltage
as the
COM
Input terminal.
Measurement Category
The safety rating of the multimeter:
1000 V, CAT I
IEC Measurement Category I. The maximum measurable voltage is 1000 Vpk in the HI -LO
terminal.
600 V, CAT II
IEC Measurement Category II. Inputs may be connected to AC mains power (up to 600
VAC) under Category II overvoltage conditions.
Measurement category definition
Measurement CAT I
applies to measurements performed on circuits not directly
connected to the AC mains. Examples are measurements on circuits not derived from the
AC mains and specially protected (internal) mains- derived circuits.
