AMETEK SLM Series Rev B - Manual (Page 30)

Operation SLM-Series AC/DC Electronic Load
3-4 M540072-01 Rev B
o VA meter with the unit as “VA”..
• Lower DM displays the lower limit of:
o Voltmeter with the unit as “Vrms”.
o Ammeter with the unit as “Arms”.
o Wattmeter with the unit as “W”.
o VA meter with the unit as “VA”.
(See 13 for upper and lower limit adjustment).
12 SENSE key and ON/OFF LED
Controls whether or not the input to the voltmeter is made from the AC input end (Sense
LED OFF) or from the Vsense end (Sense LED ON). The DM displays the voltage from
either.
13 Load Current Coarse Tuning/Fine Tuning, Increase/Decrease Keys
• During PRESET ON (see 7):
o The larger arrows ( ) coarse tune the value by larger increments/decrements.
o The smaller arrows ( ) fine tune the value by smaller increments/decrements.
• During LIMIT ON (see 11):
o 3.1.13.2.1 :Upper limit value Up/Down Key.
o 3.1.13.2.2 :Lower limit value Up/Down Key.
• When FREQ (see 15) LED lit:
o “FrEq” displayed in upper DM, keys adjust the frequency value by coarse
(larger) increments/decrements, and the keys adjust the frequency value by
fine (smaller) increments/decrements.
o “bAn” displayed in upper DM,: is Fine Tuning Up Key is Fine Tuning
Down Key.
o “Sync” displayed in upper DM, is ON Key is OFF Key.
14 √2, 2.0, 2.5, 3.0, 3.5 keys and their respective LEDs:
Each key only functions in CC mode and has no effect in CR mode.
These keys are selected to change the current C.F. (Peak Factor) of CC mode. When
changing BANK (see 15) settings, these keys will define different C.F. values.
15 FREQ key and LED
Key scrolls from FREQ to BANK to SYNC (displayed in DM) to off (LED not lit).
• Frequency and Bank can only be set in CC MODE
o FREQ (For Frequency Setting) : Setting Range: DC, 0.1 - 70.0 Hz, Auto.
o BANK (For Bank Setting ) : 0 - 10 totaling 11 banks (Not valid for DC).
• SYNC (Current Bank Sync Signal Selection):
o ON is external Sync
o OFF is internal Sync.
16 AC/DC Load Input Connector
Must not exceed the rated specification of the voltage and current of the SLM-Series
AC/DC Electronic Load.
Warning: Upon wiring, please refer to Section 3.2 to avoid damage to internal circuit and
connector.
