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 residual magnetism
remaining in the core for the DC current measurement. The Zero/Relative
function will be disabled if the MAX/MIN button is pressed.
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 5 for battery replacement.
10. Zero/Relative Symbol
When this symbol appears, it means a reference value has been subtracted from
the actual reading. The reading shown is an offseted value. Press and hold the
zero button for 2 seconds to disable this function.
11. Data Hold Symbol
Once this button is pressed, this symbol appears on LCD.
12. Bargraph
Bargraph has forty segments. It displays segments proportional to the actual
reading. Each segment represents one counts.
13. Max/Min Hold Symbol
Once the max/min button is pressed, either MAX or MIN shall be displayed on
LCD
14. Continuity Symbol
If ohm and continuity function is selected, this symbol shall appear on LCD.
15. Units Symbols
Once a function is selected, corresponding unit (V, Ω, A, or Hz) shall be displayed
on LCD.
16.V,Ω, Hz 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
meter.
