4000 Counts DMM / Peak
3.2. HOLD and Delayed Hold Feature
HOLD mode makes the meter stop updating the LCD panel. This mode can be nested in most of
the special modes. Enabling HOLD function in automatic mode makes the meter switch to manual
mode, but the Full-Scale range remains the same. ES235 provides a Delay HOLD feature. To activate
Delay HOLD feature, press down the HOLD bottom and last for 2 seconds. The meter will delay for
6 seconds, than enters HOLD mode. In the 6-secnod delayed time, the HOLD symbol on LCD panel
will blink. HOLD function and the delayed state can be cancelled by changing the measurement
mode, pressing RANGE, or push HOLD again.

See Section “Measurement Mode Switching” for the function of this pin.
3.4. REL + HOLD
In REL mode, the LCD panel displays D_N+K - D_N, where N = 1, 2, 3, … , D_N is the last value before
REL key is pushed, and D_N+K is the current value. The meter returns to normal operation if REL is
pressed again. Pressing HOLD in REL mode makes the meter stop updating the LCD panel.

Note:
1. It’s possible that relative value (D_N+K - D_N) exceeds 4,000 or -4,000 counts. The LCD shows OL in REL mode only
if D_N or D_N+K is more than 4,000 counts.
