1. Display:
3 1/2 digit LCD (1999)
2. Function switch:
A switch that selects the different
function modes or thresholds. To ensure a long
battery life, turn off the device when not used.
3. "SELECT" button:
To choose between AC and DC
voltage, or resistance/diode/continuity modes.
4. "HOLD" button:
By pressing this button the
measured result on the screen is held. You can
continue measuring with another press of this
button. This button also starts the device when it is
in standby mode.
5. "
