Instruction Manual pH 510/ Ion 510

4.4 HOLD Function

This feature lets you freeze the value of the measured reading. HOLD can be used anytime when in [MEAS]

mode. You can store the held reading into memory by pressing MI key.

4.5 Storing and Recalling Data from Memory

The meters allow up to 50 data sets to be stored and recalled into its non-volatile memory in the Last-In-First-

Out (LIFO) sequence. The data set is also stored with specified location as indicated on the display. However

you can selectively view the data at that specified location for added convenience.

pH 510 meter:

• pH and Temperature

• mV (or Relative mV) and temperature

Ion 510 meter:

• pH and Temperature

• mV (or Relative mV) and temperature

• ion and mV

For example you can store 32 pH and 18 mV values for the pH 510 or 15 ion, 12 mV and 23 pH values for the

Ion 510.

HOLDing a measurement

To hold a measurement, press the HOLD key while in measurement

mode. [HOLD] annunciator will appear on the display.

Releasing a Held Value

To release the held value, press HOLD key again. [HOLD] annunciator

will disappear from the LCD. Continue to take measurements.

Memory Input

This feature allows you to store measurement readings into memory for

later review. This mode can be invoked at any time during measurement

mode or when the reading is frozen ([HOLD] annunciator is displayed on

LCD by the activation of HOLD key).

To store reading:

1. During any measurement or HOLD function, press the MI key once

to input data into the memory.

2. [MEM] annunciator, “StO” and memory number will flash

momentarily. The meter then returns to the measurement mode.

3. To continue storing data, press MI key again.

NOTE: If the memory is full, the first value stored will be erased to

create space for the new value.
