7.1 Setting the Mode (To use the instrument as a voltmeter)
118
When mode is selected
• The maximum input voltage is DC 50 V/AC 50 Vrms. Attempting to mea-
sure voltage in excess of the maximum input could destroy the instru-
ment and result in personal injury or death.
• Ensure that the input does not exceed the maximum input voltage or cur-
rent to avoid instrument damage, short-circuiting and electric shock
resulting from heat building.
• When the instrument is used as a voltmeter, it does not function as a leakage
current tester.
• The auto range is not available when a 0.1 Hz frequency range setting is
made. Setting the frequency range to 0.1 Hz in voltmeter mode engages the
hold range (500.0 mV range).
The instrument ordinarily operates as an ammeter, but the voltmeter
function can be selected on the mode setting screen.
By using the instrument as a voltmeter, it is possible to connect an origi-
nal network if networks A through G do not conform to the required net-
work configuration.
The instrument can also be used as a general high-frequency voltmeter.
Selecting displays the voltmeter mea-
surement screen. The voltage measurement screen starts
voltmeter measurements. Measurement conditions can be
changed during measurement.
Select the measurement range.
Select the target voltage.
Press to return to the mode setting screen.
Setting to voltmeter mode results in an open internal network circuit.
The input voltage between terminals T1 and T2 can be measured.
T2 Becomes a Hi terminal.
T1 Becomes a Lo terminal.
The CAL key appears when a measurement frequency
from 0.1 Hz is set.
To obtain a more accurate measurement, press the CAL
key once before starting measurements.
When the frequency measurement range is set to 15 Hz to 1 MHz, ACPEAK is
displayed as a valid measurement voltage option.
