5. When the rotary switch is set at the
position the instrument will compare the measured
value with the high and low values. If the measurement is higher than the HI value, the unit will
beep
and show "HI --" in the upper row of LCD. If the current measurement is lower than the
LO value, the unit will beep and show "LO-- " in the upper row of LCD.
NOTE: If the HI value is set at OL, or the LO value is set at 0, the ALARM function is disabled. The
HI or LO value can be disabled individually
NOTE: The HI value cannot be lower than the LO value. Similarly the LO value cannot be higher
than the HI value. HI value will be adjusted to LO value plus 1 if roll-over occurs. The maximum
value of LO value is HI value minus 1.
NOTE: If data logging is in progress, the beeper will be disabled to save battery power. However,
the LCD displays the warning letters of "HI—" or "LO—" if an alarm condition occurs
NOTE: The values for the high and low alarm are stored in the memory. The values will be active
when the unit is powered on and alarm mode selected.
