Voltage, frequency, current and temperature measurement
Making a voltage measurement
1. Set the Main rotary range knob to volts
(The position of the right hand rotary range knob must not be in the
position.)
2. Using two test leads, connect test leads to the L1 (+ve) and L2 (-ve) terminals

OR if using the mains plug lead SAI10:
a.
For live to neutral measurements, connect the red connector to the L1 terminal and the blue connector to
the L2 terminal
b.
For live to ground measurements connect the red test to the L1 terminal and the green connector to the
L2 terminal

Note:
When connecting all three test leads (eg phase, neutral and ground) or the mains plug test lead, the
voltage displayed is the highest of the three possible voltages.
Pressing either TEST button scrolls through L-E, N-E and L-N individual voltages. When the frequency of supply is
shown, the voltage displayed reverts to the maximum voltage across all 3 terminals.
Use the Mode
button to select mV mode.
