Note:
The instrument produces a simulation resistance up to 400Ω at
its output terminal (RTD /Ω). The method of simulating resistance output
is to send out an appropriate voltage 'Vx' according to the excitation
current 'Ix' produced by the calibrated instrument. Because R (set
resistance) = Vx (output voltage) / Ix (excitation current), the calibrated
device must provide an excitation current tothe simulator. The excitation
current should range from 0.5mA to 2mA.
Note:
When testing the resistance output of a 4-wire system while
employing a 2-wire connection, you should take into consideration the
error (approx. 0.1Ω) arising from the lead resistance of the test leads. If
the capacitance between the resistance output terminal of the simulator
and the tested instrument is more than 0.1μf, the simulator will produce
improper resistance.
Battery Replacement
When the battery symbol,
, appears on the display, the battery needs to
be replaced. In order to replace the battery, proceed with the following steps.
1. Ensure that the meter is turned OFF
and remove any test leads from the
meter's terminals.
2. Lift the tilt stand on the back of the unit
to access the battery compartment
door which can be removed using a
Phillips head screwdriver.
3. Replace the 2 x AA batteries in the lid
of the battery compartment.
4. Reinstall the compartment lid by ensuring that battery terminals
touch the unit's contact points and snap into place.
5. Tighten the screw to secure the battery compartment cover.
Note:
Ensure battery door is closed and secured in place before using
the meter. To ensure proper operation, please wait 5 seconds before
turning meter on after changing batteries.
