The hold feature is used to freeze the display. When the contacts are shorted,
the display will “Hold” the last reading until the short is removed. It is recom-
mended that a mechanical switch or relay be used to activate the hold circuit,
solid state relays may give unexpected results. The hold circuit cannot be ex-
ternally powered.
No terminal can be above earth ground by more than 250Vrms. An external
fuse is recommended for safe operation, for AC supply, Slow Blow fuse at
.25A, Littlefuse Part No. 313.250 or equal. For DC supply Slow Blow fuse at
1.25A, Littlefuse Part No. 3131.25 or equal.
Hazardous voltages may be present. Disconnect power before making or re-
moving connections.
