displayed) and releases the reading when pressed a 

second time.

Warning

To avoid possible electric shock or personal injury, 

when Display HOLD is activated, be aware that the 

display will not change when you apply a different 

voltage.

Press   ZERO (HOLD) > one second to clear last 
reading from the display (   is displayed) and establish 
a baseline for applicable selected functions.

DC-Zero mode for dc and ac+dc currents. Press   ZERO 
(HOLD) > one second to activate DC-Zero (display 
shows “dc_0” for one second). When nulled value is 
larger than ± 5 DC A, an acoustic warning (3 short 
beeps) will occur.

REC / PEAK-RMS

Press REC button to activate maximum, minimum and 

average reading memory mode (   MAX MIN AVG 

is displayed). The meter beeps when MAX and MIN 

reading is updated during measurement. Press REC 

button again to read the MAX, MIN and AVG reading 

in sequence. Press REC button > one second to exit 

MAX/MIN/AVG reading memory mode.
Press REC / PEAK-RMS button > one second to enter 

PEAK-RMS mode ( 

 is displayed) to capture 

inrush current or voltage RMS values (80 ms). Press a 

second time > one second to exit.
Note: Auto Power Off is automatically disabled under 

MAX/MIN/AVG and PEAKRMS modes.

Measuring AC and DC Voltage

To measure ac or dc voltage:

1. Turn the rotary function switch to   or 
2. Press SELECT button to choose measurement function: AC V, DC V, 

DC+AC V, Hz or EF(Non contact voltage detection). The display reflects 
the chosen function mode. For Model AMP-210 and AMP-220, NCV(EF) 
function is designed in an independent rotary switch position. See the 
Non-Contact Voltage Detection chapter for details.

3. Connect the black test lead to the 

COM

 terminal and the red test lead 

to the V terminal. Before connecting the probes to the measurement 
points, add any clips to the probes that are necessary.

4. Measure the voltage by touching the probes to the desired test points 

of the circuit.

5. View the reading on the display.
6. When measuring AC voltage, press SELECT button to view the 

frequency reading on the display.
