20 Storing Measurement Values
with the METRA HIT 22M/26M/MIL
The instrument is equipped with a quartz-movement syn-
chronized measurement-value memory (128 kB), which
has sufficient capacity for an average of 50,000 measure-
ment values. Minimum capacity is 20,000 measurement
values (large signal fluctuation or time period between
measurement values). Maximum capacity is 100,000 mea-
surement values (minimal signal fluctuation, rate ≥ 0.5 s,
hysteresis = “all”). Data can be stored to intermediate
memory, or transmitted directly to a PC. Data are acquired
relative to real-time. Thus the instrument may also be used
as a real-time data logger.
The measurement data are stored as so-called data
blocks. Measurement values from the same measuring
function are stored in the same block.
Only absolute values and absolute time records can be
stored (no relative or Δ values, and no relative time
records.)
Memory content can only be read out with the help of a
PC, an infrared adapter and METRAwin

10/METRAHit

analysis software.
Preparations for Memory Mode Operation
Note!
☞
First set hysteresis, sampling rate and triggering param-
eters for memory mode operation, and then activate
the memory mode. These parameters cannot be
changed during operation in the memory mode, or
the transmission mode.
➭ Select the desired measuring function, as well as an
appropriate measuring range.
➭ Check the charging level of the battery before starting
long-term measurement value recording (see chapter
25.1, page 54).
Starting Memory Mode Operation via Menu Functions
➭ Enter the “Menu Mode” (see chapter 21, page 38).
➭ Select the main menu: StorE.
➭ The memory mode is started by activating the ↵ key.
Current memory position is displayed in %. It may range
from 00.00 to 99.99%.
➭ In order to return to the measuring function, press the
ESC|FUNC key twice. REM appears at the display.
Starting Memory Mode Operation via Shortcut
The multimeter must be switched on.
➭ Simultaneously activate the ESC|FUNC and ON keys.
REM appears at the display.
