updated. Press again, maximum value shall be displayed and updated. Zero

function will be disabled if MAX/MIN is enabled. This button is not available in duty,

hz, continuity, diode or capacitance function.

7. VΩRANGE Zero/Relative Button

On voltage or ohm function, press this button to select manual range.

On other functions, 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. This

button is not available in duty, hz, continuity, diode 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 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 offset value. Press the zero button

again 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 continuity function is selected, this symbol shall appear on LCD.

15. Units Symbols

Once a function is selected, corresponding unit (V, W , A, or Hz) shall be displayed

on LCD.

16. V, Ω, Hz, Capacitance, Temperature input Terminal

This terminal is used as input for voltage, ohm/continuity, frequency, capacitance

or temperature measurements.

17. COM Terminal

This terminal is used as common reference input.
