Omega 24 Manuale Utente

While operating as a calibrator, the unit can store and recall up to 10 output
settings (each with independent parameters, eg. °F/°C, sensor type, and res-
olution) in random access memory.

1. While in the CALIB OPR mode, depress the STORE key. Note that the

OPR annunciator is replaced by STO.

2. Next depress one of the memory location numbers (keys 0, 1, 2, . . ., 9).

The corresponding memory annunciator turns on, and the calibrator
returns to the OPR mode.

eg. STORE 2

• The enabled memory annunciator shows that the output set-up

has been saved.

• When a set up is stored in a location already in use, the new

set-up replaces the old.

• Saved set-ups are retained during power-off.

• To store a reading of 0° just hit the CLEAR while in the CALIB

OPR mode. Then depress STORE and a location number.

1.

The same performance tradeoffs apply to 2, 3 and 4-wire simulations as
to 2, 3, and 4-wire measurements. Refer to RTD, Thermistor and Ohms
Meter-Mode section above for wiring guidelines.

2. Set instrument to CALIBRATOR mode.

3. Use the sensor-select key to set the instrument to the appropriate func-

tion and range.

NOTE: To ensure accurate calibrator outputs, observe specified
limits to excitation currents. If in doubt, check current levels with
a DMM in series with either source lead (1 or 3).

NOTE: Due to limited display area, 100

Ω

and 1000

Ω

RTD's are

indicated on the display by a momentary readout of "RTD-100"
(or "RTD-1000") when first selected.

Thermistors are identified by a momentary alpha-numeric readout
of "Y-400" (signifying YSI Series-400 type thermistor).

Any of these readouts can be recalled by turning the unit off and
back on.
