Basic Measurement Function

This chapter introduces some basic measurement functions in DL-1060. You will learn
how to use your DL-1060 multimeter to measure voltage, current, resistance,
frequency, period, continuity, diode, temperature, capacitance and 2nd-Measurement
in this chapter.

2.1 Voltage Measurements (DCV & ACV)

The ranges for DC voltage measurements in DL-1060 are 100mV, 1V, 10V, 100V and
1000V. For AC voltage measurements, the ranges are 100mV to 750V AC-Coupled

T-RMS

, or 1000V peak.

Figures 2-1

shows the locations of the buttons needed and

message display for voltage measurement.

Warning: Do not apply more than 1000V (peak) to the multimeter.
Applying excess voltage may damage your meter, or cause
possible electric shock or personal injury.

※

Note: To eliminate the thermal EMFs due to the differences between two metals,

use copper leads to connect your source signal to the meter.

How to measure voltage

1.

Connect the test leads to the terminals on the front panel.

2.

Set RESOLUTION of DCV (refer to 3.1.3 Resolution & NPLC Setting), BANDWIDTH
of ACV (refer to 3.1.2.1

) or skip this step if default is to be used.

3.

Press DCV or ACV button for DC or AC voltage measuring.

4.

Select auto-range function by pressing SHIFT + ESC button on the front panel or
use

△

and

▽

buttons to manually select desired range.

5.

Connect test leads to your source signal and observe readings shown on the
display. If the input signal is beyond the allowed range, an overflow message

“OVLD” will be displayed.
