7. Zero/Relative Button
Once this button is pressed, the current reading shall be set to zero and be used as
a zero reference value for all other subsequent measurement. The function is also
used to remove offset value caused by the residual magetism remained in the core
for the DC current measurement. The Zero/Relatiive function will be disabled if the
MAX/MIN button is pressed. This button is not available i n continuity or Hz function.
8.LCD
This is a 3 3/4 digit Liquid Crystal Display with maximum indication of 3999.
Function symbols, units, bargraph, sign, decimal points, low battery symbols,
max/min symbols, and zero symbol are included.
9. Low Battery Symbol
When this symbol appears, it means the battery voltage drops below the minimum
required voltage. Refer to Section V for battery replacement.
10. Zero/Relative Symbol
When this symbol appears, it means a reference value has been subtracted from

14. Continuity Symbol
If ohm and continuity function is selected, this symbol shall appears on LCD.
15. Units Symbols
Once a function is selected, corresponding unit 0/, n , A, or Hz) shall be displayed
on LCD.
16. VnHz Input Terminal
This terminal is used as input for voltage, ohm/continuity, or frequency
measurements.
17. COM Terminal
This terminal is used as common reference input.
18. Hand Strap
Put your hand through the hole of hand strap to avoid accidental drop of the clamp
