automatically shuts the meter OFF if 17 minutes elapse without
activity.
2. If "OL" appears on the display during a measurement, the
measurement exceeds the range selected. Change to a higher range.
AC, DC or AC+DC Voltage Measurements
1. Insert the black test lead into the negative COM jack and the red test
lead into the positive V jack.
2. Set the function switch to the "VAC", "VDC" or "mV" position
3. In “VAC” press the SELECT key to toggle between AC and dBm.
4. In “VDC” press the SELECT key to toggle between DC and AC+DC.
5. In “mV” press the SELECT key to toggle between DC, AC and
AC+DC.
6. Read the voltage measurement on the display.
7. Press the 500000 key momentarily to toggle between 50,000 counts
and 500,000 counts in DCV or DC mV.
Note: The setting selected will be stored in non-volatile memory and will
become the default setting.
dBm Measurements
1. Set up and connect as described for ACV measurements.
2. Press the SELECT key momentarily to select dBm.
3. The reference impedance will be displayed for 1 second before the
dBm display appears.
4. Press the RANGE key momentarily to change the reference
impedance.
AC or DC Current Measurements
CAUTION: Do not make current measurements at 20A for longer than
30 seconds. Exceeding 30 seconds may cause damage to the meter
and/or the test leads.
